Can Algebra Be Useful?
What is Algebra?
Algebra is a comprehensive component of mathematics that uses abstraction by replacing alphabetic characters for numbers. It is this abstraction that often frightens many and quivers some. Algebra topics range from working with equations to factoring binomials all the way to finding the y-intercept. In nearly all cases, just as in any other maths associated 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.
Help!!! Exponents, Radicals and Graphing on the Way…
There are many advanced subjects. First there are exponents. 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. While working with exponents 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, simply put, is the reversing of an power. Radical expressions are denoted by the symbol “V” and when placed next to 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. Equally with exponents, radical expressions can be added, subtracted, multiplied and divided. Radicals can be changed into exponents and exponents back into radicals. If exponents and roots aren’t enough, there is always graphing. Start with graphing straight lines and deciding 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. you master the mathematical art of graphing, you will notice a whole new world filled with parabolas and hyperbolas.
Help is Out There
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 systems 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 guru in no time.
