Role of Algebra in Your Life
Algebra - what is it?
It is an area of mathematics that use letters in place 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 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 many cases, just as in any other maths related class, students begin 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.
Exponents and Radicals and Graphing Oh My!
There are many another higher level subjects. First there are exponents. An exponent is the small number placed to the right and slightly above 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 exponentiated. The above algebraic expression is read as, x plus y to the third power. In working with exponents 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 reversing of an exponent. Radical expressions are denoted by the symbolic representation “V” and when placed beside number 4, it is read as square root of 4, which is equal to 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. As with exponents, radical expressions can be added, subtracted, multiplied and divided. Radicals can be converted into exponents and powers back into radicals. If exponents and radicals aren’t enough, there is always graphing. The best way to start with graphing is to draw lines and try to work out if they are horizontal, vertical or neither. 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 identify a whole new world full of parabolas and hyperbolas.
Help is Available
If you are learning algebra and this all seems a little too much, don’t scratch. It’s time to look around because there exists a wide array of resources that is able to help you master the study. The custom is to decide on a math tutor, but the modern 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 instruments can assist you become an algebra guru in very little time.
