Algebra and Symbolic Thinking
Algebra - what is it?
It is an area of mathematics that use letters instead of numbers to derive results for a given situation. It is this abstraction that often scares many and thrills some. Algebra topics range by working through simple tasks such as factoring binomials and eventually progressing on to finding the product of matrices. In most cases, just as in any other mathematics 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 another advanced themes. First there are exponents. A power is the little number placed as superscript to a number or algebraic expression. An example is (x + y)3 where the 3 is the power and denotes the power to which that number is raised. The above algebraic expression is read, x plus y to the third power. In working with powers you can add, subtract, multiple or divide them. If you pick up the basics, you will shortly get down to working with rational and negative exponents and if you think those are not challenging enough, hopefully radicals will spin your head. A radical, in simple terms, is the reversing of an power. The V beside 4 denote a radical expression which means, the square root of 4, which equals 2. The opposite exponential equation is 2^2 which is read, 2 to the 2nd power, and equals 4. Additionally, powers can be added, subtracted, multiplied or divided by radicals. Radicals can be switched into powers and exponents back into radicals. If you find that powers and roots don’t really stimulate your interest, you could move on to graphing. Start with graphing straight lines and finding 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 discover 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 subject area. The custom is to decide on a math tutor, but the latest algebraic software are no different. In fact, they are better than math tutors. Know that frustration is not your only friend because any of these tools can help you become an algebra guru in very little time.
