Algebra to the Rescue
July 29th, 2010Let’s Explore Algebra
Algebra is a large component of mathematics that uses generalization by exchanging letters for numbers. It is this abstraction that often scares many and shudders some. topics of algebra range from working with equations to factoring binomials all the way to finding the y-intercept. Most individuals get down to try Algebra by adding, subtracting, reducing and simplifying algebraic expressions. They then move on to understanding equivalent fractions, finding Least Common Multiples (LCM) and converting fractions to decimals.
Help!!! Exponents, Radicals and Graphing on the Way…
There are many another advanced themes. To start off with there are exponents. An exponent is the tiny number placed as superscript to a number or algebraic expression. In this example (x + y)3 where the 3 is the exponent and denotes the power to which that number is exponentiated. The above algebraic expression is read as, x plus y to the third power. In working with powers you can add, subtract, multiple or divide them. You can work with rational 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 power. Radical expressions are shown by the symbolic representation “V” and when placed alongside number 4, it is read as square root of 4, which is equal to 2. The contrary exponential equation is 2^2 which is read, 2 to the 2nd power, and equals 4. As with exponents, radical expressions can be added, subtracted, multiplied and divided. Radicals can be changed into powers and exponents back into roots. If exponents and roots aren ‘t enough, there is always graphing. Start with graphing straight lines and finding if the line is horizontal or vertical or neither. Does the line have an x-intercept or a y-intercept? Can you find the slope of the line? you master the mathematical art of graphing, you will identify a whole new world full of parabolas and hyperbolas.
Help is Available
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 discipline. The tradition is to settle for a math tutor, but the up-to-date algebraic software are no different. In fact, they are as good as math tutors. You can also use algebra calculators or algebra solvers. any of these tools can assist you become an algebra guru in no time.
