Getting Help with Algebra
Algebra - what is it?
It is an domain of mathematics that use letter of the alphabets in replacement of numbers to derive results for a given situation. It is this abstraction that often scares many and shudders some. Algebra topics range from working with fractions to factoring binomials all the way to finding the inverse of a matrix. In many cases, just as in any other maths related class, students begin by adding, subtracting and simplifying algebraic expressions . They then move on to understanding equivalent fractions, finding Least Common Multiples (LCM) and converting fractions to decimals.
Oh no! It’s Exponents, Radicals and Graphing
There are numerous advanced subjects. First there are exponents. An exponent is the small number placed as superscript to a number or algebraic expression. An example is (x + y)3 where the 3 is the power and refers the power to which that number is exponentiated. The above algebraic expression is expressed as, x plus y to the third power. While working with powers you will often come across exercises that require you to add, subtract, multiply and divide. You can work with fractional and negative exponents. If that isn’t enough to make your head spin, then you can move on to radicals. A radical, in simple terms, is the undoing of an exponent. Radical expressions are referred by the symbolic representation “V” and when placed next to number 4, it is read as square root of 4, which is equal to 2. The inverse exponential equation is 2^2 which is read, 2 to the 2nd power, and equals 4. Additionally, exponents can be added, subtracted, multiplied or divided by radicals. Radicals can be converted into powers and exponents back into roots. If you find that exponents and roots don’t really stir your interest, you could move on to graphing. The best way to start with graphing is to draw lines and try to work out if they are horizontal, vertical or neither. Another question to ask is whether the line has an x-intercept or a y-intercept Furthermore, try and see if you can find the slope of a line . you master the mathematical art of graphing, you will come across a whole new world full of parabolas and hyperbolas.
Help is Out There
While you are learning algebra if the terms and concepts seem too much to handle, relax and take a break. It’s time to look around because there exists a wide array of resources that is able to help you master the subject. Look for math tutors or software programs that will walk you through gradual process on how to solve any problem. Know that frustration is not your only friend because any of these tools can assist you become an algebra expert in very little time.
