Why You Need to Know Algebra?
Algebra – what is it?
Algebra is a wide category of mathematics that uses abstraction by replacing letters for numbers. It is this abstraction that often frightens many and shudders some. Algebra topics range from working with equations to factoring binomials all the way to finding the y-intercept. Most people start to learn Algebra by adding, subtracting, reducing and simplifying fractions . 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.
Help!!! Exponents, Radicals and Graphing on the Way…
There are numerous higher level subjects. To start off with there are exponents. A power is the small number placed as superscript to a number or algebraic expression. An example is (x + y)3 where the 3 is the exponent and denotes the power to which that number is exponentiated. The above algebraic expression is read, 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 exponent. Radical expressions are referred by the symbol “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 switched into powers and exponents back into roots. If exponents and roots aren’t enough, there is always 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. you master the mathematical art of graphing, you will chance on a whole new world full of parabolas and hyperbolas.
Need Help?
While you are learning algebra if the terms and concepts seem too much to handle, relax and take a break. There are many resources out there that can help you master complex inequalities, quadratic formulas and polynomials. The custom is to decide on a math tutor, but the up-to-date 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 instruments can assist you become an algebra expert in very little time.
