Let’s Explore Algebra
Algebra is a comprehensive branch of mathematics that uses abstraction by replacing alphabetic characters for numbers. It is this abstraction that often frightens many and shudders some. topics of algebra range from working with inequalities to factoring binomials all the way to finding the inverse of a matrix. Most people start to try Algebra by adding, subtracting, reducing and simplifying fractions. later on, they would move on to more advanced stages of solving algebraic equations using the least common multiples and converting fractions in to decimals.
Exponents and Radicals and Graphing Oh My!
There are many advanced topics. Firstly there are exponents. An exponent is the tiny number placed as superscript to 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, x plus y to the third power. In working with powers 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, simply put, 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. Additionally, exponents can be added, subtracted, multiplied or divided by radicals. Radicals can be switched into powers and exponents back into roots. If exponents and radicals aren’t enough, there is always 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? you master the mathematical art of graphing, you will discover 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. It’s time to look around because there exists a wide array of resources that is able to help you master the theme. The custom is to decide on a math tutor, but the latest algebraic software are no different. In fact, they are as good as math tutors. You can also use algebra calculators or algebra solvers. any of these instruments can assist you become an algebra expert in no time.
