Knowing Algebra
What is Algebra?
Algebra is a comprehensive part of mathematics that uses abstraction by replacing letters for numbers. 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 pupils find it fun to play around with. topics of algebra extend from working with equations to factoring binomials all the way to finding the inverse of a matrix. In almost 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.
Exponents and Radicals and Graphing Oh My!
There are many another advanced topics. Firstly there are powers. A power is the small 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 expressed as, x plus y to the third power. In working with exponents you can add, subtract, multiple or divide them. 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 undoing of an power. The V beside 4 denote a radical expression which means, the square root of 4, which equals 2. The contrasting exponential equation is 2^2 which is read, 2 to the 2nd power, and equals 4. Moreover, powers can be added, subtracted, multiplied or divided by radicals. Radicals can be converted into powers and exponents back into roots. If you find that powers and radicals don’t really stimulate your interest, you could move on to graphing. The best way to start with graphing is to draw lines and try to figure 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. After you master graphing lines, a whole world of circles, parabolas and hyperbolas awaits you!
Help is Out There
If you are learning algebra and this all seems a little too much, don’t sweat. 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 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 expert in no time.
