Algebra – what is it?
It is an domain of mathematics that use letter of the alphabets in replacement 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 equations to factoring binomials all the way to finding the y-intercept. In almost all cases, just as in any other mathematics related class, students start 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 advanced themes. Firstly there are exponents. An exponent is the little number placed to the right and slightly above a number or algebraic expression. In this example (x + y)3 where the 3 is the power and refers 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. 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, in simple terms, is the reversing of an exponent. 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. Equally with exponents, radical expressions can be added, subtracted, multiplied and divided. Radicals can be switched into powers and exponents back into radicals. If powers and radicals aren’t enough, there is always graphing. Start with graphing straight lines and verifying 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? you master the mathematical art of graphing, you will chance on a whole new world filled with 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. Did you know that there are many resources out there that can help you master complex systems of equations, quadratic formulas and polynomials. Look for math tutors or software systems that will walk you through gradual process on how to solve any problem. You can also use algebra calculators or algebra solvers. any of these instruments can assist you become an algebra expert in very little time.
