Why You Must Learn Algebra
What is Algebra?
It is an domain of mathematics that use letters instead of numbers to derive results for a given situation. This abstraction is the very reason why most people find algebra scary and too difficult to handle and it is the same reasons why some students find it fun to play around with. Algebra topics range from working with inequalities to factoring binomials all the way to finding the inverse of a matrix. In almost all cases, just as in any other maths oriented class, students start by adding, subtracting and simplifying algebraic expressions. later on, they would move on to more advanced stages of solving algebraic equations using the greatest common factors and converting fractions in to decimals.
Oh no! It’s Exponents, Radicals and Graphing
There are numerous higher level subjects. Firstly there are exponents. An exponent is the tiny number placed to the right and slightly above a number or algebraic expression. In this example (x + y)3 where the 3 is the exponent and refers the power to which that number is raised. 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. 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 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. Moreover, powers can be added, subtracted, multiplied or divided by radicals. Radicals can be converted into exponents and powers back into roots. If you find that powers and radicals don’t really stimulate your interest, you could move on to graphing. Start with graphing straight lines and defining if the line is horizontal or vertical or something else. Another question to ask is whether the line has an x-intercept or a y-intercept Can you find the slope of the line? Once you master graphing lines, a whole world of circles, parabolas and hyperbolas awaits you!
Help is Available
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 discipline. 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. You can also use algebra calculators or algebra solvers. any of these tools can assist you become an algebra expert in no time.
