Calculating the Role of Algebra

Filed under:Education Special, Mathematics Tips, Science Parlor — posted on February 15, 2010 @ 11:10 pm

An comprehensive research carried out to figure out the reasons behind school dropouts shows that many individuals look at algebra as the culprit. The proficiency of knowledge of the teacher is not merely adequate for pupils to understand the algebraic concepts, nor it is adequate to rekindle interest about the field of study. It’s the method; the content is explained to its pupils which leads a lot for developing interest in the contents.

What is Algebra?

A concise introduction of Algebra would be a subdivision of mathematics which substitutes letters for numbers; algebraic equation is a scale. The basic theories of algebra includes real numbers, complex numbers, matrices and vectors.

The Different Fields

Generally, algebra spreads across many domains of mathematics. for example; Multiplying exponents, dividing exponents, Solving linear inequalities , Finding Greatest common factor or GCM, Multiplying, Adding, Subtracting fractions and many more.

If the above mentioned domains are already making you nervous, I hope that the definitions to follow will ease your anxiety and give real perception in to the subject.

Exponents are just shorthand for referring multiplication of identical factors. Fractions are equally interesting and actually are used when representing numbers that describe the parts of a whole. Many such similar areas in algebra may sound fearful at the beginning, but once you comprehend the simple concept behind it, you will be captivated by its purpose. To state a few more - Mixed numbers, Quadratic formula, Graphing linear inequalities , solving compound in equalities , Factoring binomials, and Factoring polynomials; are all algebraic expressions.

Although you may find it puzzling to understand mixed numbers, you may be astonished to find out that they are a type of fractions. Similarly, graphing linear equalities may be self explanatory and there are many other similar algebraic expressions that may sound complex but are extremely interesting to work with.

Finding a Tutor

If you want to quench your thirst for algebraic knowledge further and you do not have any instructors there is nothing to worry about. Because There are online lessons too. These lessons stress the practicalities instead of technicalities, demonstrating time-tested techniques. The algebra solver software can guide you stepwise in working out your maths sums and it can also provide explanations of all steps.

Algebra in Our Education

Filed under:Education Special, Mathematics Tips, Science Parlor — posted on September 9, 2009 @ 5:43 pm

It is algebra that we employ to get our everyday things done. The mankind forever continues counting, measuring, dividing, and multiplying.

The History

Invented in the first millennium BC, algebra was first invented in the middle-east. The ancient brains applied algebra for solving day-to-day problems while the Asian or rather Chinese counterpart utilized geometry for the same intention.

The Nature of Algebra

Although you may see algebra as solving formulas, simplifying rational expressions, and converting fractions to decimals, algebra has a much larger body of knowledge and applicability. Since this aspect has been understood, the education system pressures us to learn algebra from the beginning of our student life.

Algebra I

The students are given an intro in this study course to numbers, solving linear equations , graphing systems of linear equations, graphing linear inequalities, laws of exponents, resolving linear equations, and factoring polynomials. This is the founding level course for all the other levels of algebra.
If a student is keen on studying algebra down to its roots, then this is the most central study course.

Algebra II

Once the pupils are competent with Algebra I constructs, Algebra II can be taken up for expanding the spectrum of this extraordinary segment of mathematics. There are two views of Algebra II; emphasizing more on the topics learned in Algebra I and introduction to new concepts. When it comes to the new introductions, adding and subtracting matrices, quadratic functions, resolving exponential equations , probability and statistics are important.
In this stage of study, pupils are supposed to focus more on the core concepts.

College Algebra

This is one of the most serious stages of learning Algebra with nearly no new topic introduced. I assume it is quite comic, but this is the nature of mathematics. Mathematics is called the queen of all sciences. Do you know why? That’s because of the irregular nature of mathematics!

How to get aid on Algebra?

Algebra has the most wide-ranging methods and tools available for getting help. The first and the foremost primary source is an Algebra tutor from whom you can get help and aid.
In addition to the above methods, one should never undervalue the use of Algebra computer software that is particularly designed to solve algebraic problems with informative steps. This software program really brings insight in to Algebraic procedures of solving equations, by providing pupils to simply watch and learn through examples.

Is Algebra Too Hard?

Algebra is good at differentiating relationships between things that vary from time to time. For example, the relationship between a person’s income and rise of his expenses could be found and estimated using elementary algebraic equations. Math is not an easy subject for many pupils. Many software programs are available with a miscellanea of study introduction so students of any intellect level can find the way that works for him/her. These applications also helps students to understand importance of Algebra in real life as well as in industry field. Wider functions applied in algebra include Graphing radical inequalities, Solving compound inequalities , Solving quadratic inequalities, Adding and Subtracting matrices etc.
Algebra is an important course but students can be weak-kneed initially if they do not work hard enough in early stages. This makes foundation math skills essential to help students successfully pass algebra and progress into graduate math with assurance.

How to Successfully Deal With Algebra

Instrumental algebra software applications offer more than what can be found in the students textbook, such as homework help, interactive lesson plans, games and a worksheet tool or graphing calculator. The most useful software have all of these constituents - ease of use and covering of all the topics.

The educational activity tools are always useful when methods like text, audio, animation, video and games are put in to use. Schools and colleges require that students complete algebra courses from pre-algebra to algebra II. Important topics normally include: Finding complement of an angle, inverse of functions, finding degree of polynomial, determine if line is Factoring sum of cubes, Simplifying radical expressions , Solving exponential equations and Solving system of equations by addition etc.

How to Use Algebra Software

Some algebraic software shows results only, while other (most suitable for elementary use of algebra) show all the steps as well as explanations of math basics that are in use. Students mostly concern over the ease of use of software. Thus, the software better be loaded with value added features like high quality and timely user support, integrated help options, and easy to understand math wizards.

What Is so Difficult about Algebra?

Filed under:Education Special, Mathematics Tips, Science Parlor — posted on May 27, 2009 @ 4:05 pm

Algebra is one of the essential branches of mathematics which studies structure, relation and quantity. Algebra works with numbers, symbols, elements and variables. Fundamental algebra is a foundation to constructs in algebra like solving fractional equations, understanding polynomials along with factoring binomials, trinomials and polynomials as well as the determination of their roots.
Linear inequalities are the easiest to solve. Simultaneous equations with two or three variables is an extension of linear equations . As we advance further in the sequence to quadratic, bi-quadratic and cubic equations, they turn more and more complicated to solve.

The Origin of Algebra

Everyone who is keen on studying algebra needs to go through elementary algebra as it lays the groundwork for intermediate or college algebra. Apart from addressing mathematical expressions, it also consists of all kinds of equations like linear, quadratic and cubic. In algebra, all shapes such as a circle, hyperbola or parabola are presented by equations.
The equations can be solved for different combinations by producing a graph. Lines are the product of graphing simple linear equations. It is quite simple to solve systems of equations when represented graphically. Two or more equations with the same number of variables are normally known as a system of equations. They can be both linear and non-linear. Systems of equations with inequalities (example; x>y) when graphed gives an region on the graph which matches the inequality condition.

Matrices help solve a set of complicated problems like the ones existing in electrical networks. A matrix is a rectangular array of numbers organized in rows and columns. The numbers in a matrix are known as entries. Several operations like addition, multiplication and decomposition can be performed on matrices thereby offering theoretically and practically usable mathematical answers.

Help for Algebra

Due to the sound theoretical and practical background, algebra acts as the spine for numerous other sciences. The invention of computers has made algebra simpler than what it was and therefore it has got an all different critical position. Algebra is not as complicated as it may sound. There is a lot of help and tutorials available to help you over the algebra lessons.
Net resources like algebra solver software program are interactive, present algebra lesson and assistance you solve numerous things attached to algebra from Algebra-1 to College Algebra. If you have not followed something in the algebra course of study or sense that you have missed an essential mathematical concept, online tutors, web resources, and online algebra courses of study can offer you that extra help. Algebra calculators guide you over your homework with a stepwise calculations and explanations with illustrations. You can improve your knowledge with the aid of the interactive tools. You can also appraise your knowledge at the end of a lesson by taking the test.

Algebra Opens Your World

Let’s Explore Algebra

It is an area of mathematics that use letters in place of numbers to derive results for a given situation. It is this abstraction that often frightens many and thrills some. Algebra topics range by working through simple tasks such as factoring binomials and eventually progressing on to finding the inverse of a matrix. Most people get down to learn Algebra by adding, subtracting, reducing and simplifying fractions . later on, they would move on to more advanced stages of solving algebraic equations using the least common multiples and converting fractions in to decimals.

Exponents and Radicals and Graphing Oh My!

There are many another higher level subjects. First there are powers. A power is the little number placed as superscript to a number or algebraic expression. In this example (x + y)3 where the 3 is the power and refers the power to which that number is exponentiated. The above algebraic expression is read, x plus y to the third power. In working with exponents you can add, subtract, multiple or divide them. If you pick up the basic principles, you will soon start working with rational and negative powers and if you think those are not challenging enough, hopefully complex number will spin your head. A radical, in simple terms, is the undoing of an power. The V beside 4 denote a radical expression which means, the square root of 4, which equals 2. The inverse of “V” symbol is “^” which denotes that the number it refers to is a multiple of the principle number. Therefore, 2^2 which is read as 2 to the 2nd power, equals 4. Additionally, exponents can be added, subtracted, multiplied or divided by radicals. Radicals can be converted into exponents and powers back into roots. If powers and roots aren’t enough, there is always graphing. Start with graphing straight lines and determining if the line is horizontal or vertical or something else. Does the line have an x-intercept or a y-intercept? Furthermore, try and see if you can find the slope of a line. Once you master graphing lines, a whole world of circles, parabolas and hyperbolas awaits you!

Want Help?

If you are learning algebra and this all seems a little too much, don’t fret. It’s time to look around because there exists a wide array of resources that is able to help you master the content. Look for math tutors or software packages that will walk you through step-by-step process on how to solve any problem. Know that frustration is not your only friend because any of these tools can help you become an algebra expert in very little time.

Be Careful of Inquiries on Your Credit Report

Filed under:Mathematics Tips — posted on June 14, 2008 @ 8:06 pm

Every time that someone looks at your credit report, the inquiry is noted. If you have lots of inquiries on your report, it may appear that you are shopping for several loans at once - or that you have been rejected by lenders. Both make you appear a poor credit risk and may affect your credit score. This means that you should be careful about who looks at your credit report. If you are shopping for a loan, shop around within a short period of time, since inquiries made within a few days of each other will generally be lumped together and counted as one inquiry.

You can also cut down on the number of inquiries on your account by approaching lenders you have already researched and may be interest in doing business with - by researching first and approaching second you will likely have only a few lenders accessing your credit report at the same time, which can help save your credit score.

Be careful of online loan rate comparisons.

Online loan rate quotes are easy to get - type in some personal information and you can get a quote on your car loan, personal loan, student loan, or mortgage in seconds. This is free and convenient, leading many people to compare several companies at once in order to make sure that they get the best deal possible.

The problem is that since online quotes are a fairly recent phenomenon, credit bureaus count each such quote estimate as an “inquiry.” This means that if you compare too many companies online by asking for quotes, your credit score will fall due to too many “inquiries.”

This does not mean that you shouldn’t seek online quotes for loans - not at all. In fact, online loan quotes are a great resource that can help you get the very best rates on your next loan. What this information does mean, however, is that you should research companies and narrow down possible lenders to just a few before making inquiries. This will help ensure that the number of inquires on your credit report is small - and your credit rating will stay in good shape.

Credit Cards 101

Filed under:Mathematics Tips — posted on April 21, 2008 @ 7:38 pm

What’s a credit card?

A credit card is an agreement between you and a financial group, such as a bank, that you will pay them back in the future so that you can spend the money first. The financial group lends you the money you need and in return expects you to pay them back over a period of time. A credit card is a great financial tool. It can be more convenient to use and carry than cash and it offers you valuable consumer protections under federal law.


How to Qualify for a Credit Card
If you’re at least 18 years old and have a regular source of income, you are well on your way to qualifying for a credit card. If you’ve financed a car loan or other purchase, you probably have a record at a credit reporting bureau. This credit history shows how responsible you’ve been in paying your bills and helps the credit card issuer decide how much credit to extend.


How to choose a credit card?
The first thing to consider is the interest rate on your credit cards. Low interest rates credit cards are always the best choice. Shop around to find the credit cards that offer lowest interest rates. Once you have a low interest rate card, get rid of your higher interest rate cards.


Getting a reward card. Reward cards offer the same purchasing ability as regular credit cards but also allow you to enjoy rewards from points earned or immediate discounts on purchases at select retailers. The secret to finding the best reward card for you is to get a card that offers rewards from a vendor you normally shop at anyway. For example, if you buy a lot of petrol, get a card from a vendor that gives you points for filling up your car with petrol.


Annual Fees. Many credit card issuers charge an annual fee for granting you credit. But there are also many issuers charge no annual fee.


Establishing a Good Credit History
After you’ve received your credit card, pay your bills on time - you’ll establish a good credit history.

What is a Credit Report

Filed under:Mathematics Tips — posted on April 16, 2008 @ 11:59 pm

This article is a concise, informative tell-all explaining what exactly a credit report is, and what that means to you. It will NOT inform you where to get a cheap, or free, credit report. Rather, this article will explain what types of credit reports are available, and why they are used.

A credit report is a retelling of your credit payment history. It can be provided to companies by one of the four credit bureaus in the U.S. as designated by law. Usually, this information is only shared when credit is being extended, although this is not always the case.

A credit report is used to tell a potential creditor about your ability to repay your debts, based on past experiences. All credit reports are hosted in databases housed by the credit bureaus.

If you are one of the 210 million people in the U.S who has a student loan, credit card, mortgage or another type of loan, then you probably have a credit file, somewhere. The information gathered to create your credit file is garnered from the companies with which you have credit extended to you. Also, the government or legal system may provide information as well.

Whenever you apply for more credit, a credit report is usually created which contains all of this information from one of the four credit bureaus in the U.S. (Innovex, Experian, Equifax and TransUnion). There are quite a few other, smaller credit bureaus around the states; however, most credit granting agencies will only look at information from one of the big four.

There are several different kinds of credit reports that an agency can request about you:

- Consumer Credit Reports (what we have discussed most of this article already);
- Property Manager Credit Reports: These reports are used by landlords to determine your credit history with regards to your rental payments, and are essentially the same report as the consumer credit report.
- Business Credit Reports: These reports are used by credit agencies to determine if a business is credit worthy. Information gathered can include company background, number of employees, estimated yearly sales, public records, payment trends and how the company compares to others in the same industry.
- Employer Credit Reports: These reports are similar to the consumer credit reports, but are used in addition, and include such information as employment history, education, criminal records checks, and motor vehicle registration and history.
- Mortgage Broker Credit Reports: These credit reports are quite different than the others, as they bring together information from more than one database at a time. These are used to determine if a client is a good credit granting risk for a mortgage, and can include information such as your name, living situation, and employment and educational history.

Credit bureaus collect information about the people who have credit, and then maintain that information for any reports as discussed above. Although credit bureaus are not affiliated with the government, they are strictly regulated to protect the privacy of credit issuers, granters and consumers.

Cash Back Credit Card: How Rewarding Is It?

Filed under:Mathematics Tips — posted on April 11, 2008 @ 4:11 am

As the credit card market becomes more competitive than ever, banks and lending institutions are coming up with new marketing and financial strategies to obtain more customers. One of those strategies used to acquire more customers is through the use of a cash back credit card.

By definition, those are credit cards that will return a fixed percentage of cash back to the customer according to the amount of purchases charged on the credit card. Usually, the cash back rebate is typically anywhere between 1 to 2% and is computed within a given time frame. Therefore, cash back credit cards might result in a good saving tool if used properly and conscientiously.

Let’s assume that a given person will use his/her credit card and will also carry a monthly card balance. If the ongoing interest rate is very high, the finance charges will or than likely offset any of the savings gained from the cash rebates. On the other hand, if the card balance is paid in full at the end of every grace period, the cash back rebates earned from the credit card will usually end up earning the cardholder money back and sometimes a significant amount depending on how often the card is used.

Cash back credit cards will payout the cash rebates earned either by crediting the actual earned rebate back against the existing card balance or will pay the cardholder with a rebate check, usually in $50 to $100 increments.

With the notion of accumulating cash with card purchases, people will psychologically tend to use their credit cards more than other payment options. Very often, cardholders will set a specific time frame for their card purchase activities in order to accumulate the most cash rebates possible. As more and more companies accept credit cards, cardholders are becoming more and more comfortable with using their respective cards to pay virtually everything including utility bills, mortgages and rent payments. With a 1% to as high as a 5% cash back bonus on all purchases, cardholders anticipate some hefty savings from a cash back credit card.

Not surprisingly, cash back credit cards are very popular with consumers. But cardholders must be wary of using them correctly, if they wish to derive maximum benefit. Banks and credit card issuers typically design the cards to maximize their own profit not the consumers profit because card issuers anticipate the cards will not be used efficiently by some, if not many of the cardholders utilizing these cards.

Cash back credit cards are among the many financial tools that can be truly rewarding for cardholders that use the cards effectively and look beyond just the pure attraction of receiving cash back. If cardholders are vigilante about paying off their card balances each and every month, they can potentially rack up significant savings from a cash back credit card. But if not, they might end up paying out significantly more in finance charges over time than their old credit card.

Five Things You Should Know About Contactless RFID Credit Cards

Filed under:Mathematics Tips — posted on April 6, 2008 @ 6:32 pm

What is a contactless credit card and how does it work?

For decades, credit cards have relied on magnetic stripes located on the reverse side of the card to store data. To transmit this data, the card must be swiped through a magnetic reader, making physical contact with the stripe. A contactless credit card, on the other hand, stores its data on a chip embedded in the card’s plastic. This data is transmitted not magnetically, but rather via a tiny radio signal when the card comes in close proximity of a special reader at the checkout stand. This works through radio frequency identification technology, also known as RFID. When the chip comes close enough to the reader, an antenna on the chip is jolted to life by the electromagnetic field created by the reader, and transaction data is sent to into the system.

What are the advantages of contactless credit cards?

For starters, these RFID credit cards are much faster and more convenient than traditional magnetic stripe cards. A cardholder simply waves the card over the reader, waits a moment for the acceptence signal from the machine, and that’s it. There’s no need to fumble for cash, and with transactions under $25, there is no need to key in a PIN code or sign a receipt. Just wave and go. Also, since the card never leaves the user’s hand, it is considered by some to be more secure.

What are the disadvantages of contactless credit cards?

Some opponents to contactless credit cards have contended that there are security risks with using these RFID credit cards, as the radio transmission could potentially get intercepted by a criminal with malicious intentions. The good news, however, is that the actual credit card number is not transmitted via radio wave. Rather, it is a unique encrypted code only good for RFID transactions. Also, just like ordinary cards, cardholders are not liable for any fraudulent charges.

Where can contactless credit cards be used?

Currently, Visa Contactless, American ExpressPay, and MasterCard PayPass are available at select retailers in certain locations in the United States, including 7-Eleven, McDonald’s, KFC, Arby’s, Walgreens, Sony Style, Wawa, Sheetz, CVS Pharmacy, and a variety of movie theaters. Retailers capable of handing contactless credit card transactions will have a special symbol on their credit card reader located at the checkout stand. RFID credit cards can also be used at any location that accepts ordinary credit cards, since the new contactless cards will still have a regular magnetic stripe on the back.

Who offers contactless credit cards?

All new American Express Blue and Blue Cash cards now come equipped with the contactless feature. Also available from American Express is an RFID key fob that can be linked to most existing credit card accounts. Chase has teamed with MasterCard and Visa to offer Chase blink cards in a variety of styles.

Joey Loma recommends Find Credit Cards to apply for a contactless RFID credit card.
