Algebra Is More Important than You Think
What is Algebra?
It is an area of mathematics that use letters in place of numbers to derive results for a given situation. It is this abstraction that often frightens many and quivers some. Algebra topics range by working through simple tasks such as factoring polynomials and eventually progressing on to finding the product of matrices. In almost all cases, just as in any other maths associated 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 least common multiples and converting fractions in to decimals.
Help!!! Exponents, Radicals and Graphing on the Way…
There are numerous higher level topics. First there are powers. A power is the little number placed to the right and slightly above a number or algebraic expression. An example is (x + y)3 where the 3 is the exponent and refers the power to which that number is exponentiated. The above algebraic expression is expressed as, x plus y to the third power. While working with exponents you will often see exercises that require you to add, subtract, multiply and divide. If you pick up the fundamentals, you will soon start working with rational and negative exponents and if you think those are not challenging enough, hopefully complex number will spin your head. A radical, simply put, is the reversing of an power. Radical expressions are shown by the symbolic representation “V” and when placed alongside 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. Additionally, powers can be added, subtracted, multiplied or divided by radicals. Radicals can be changed into powers and powers back into radicals. If you find that exponents and roots don’t really brace 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 Can you find the slope of the line? you master the mathematical art of graphing, you will find out a whole new world full of parabolas and hyperbolas.
Help is Out There
If you are learning algebra and this all seems a little too much, don’t fret. It’s time to look around because there exists a wide array of resources that is able to help you master the study. Look for math tutors or software packages that will walk you through gradual process on how to solve any problem. Know that frustration is not your only friend because any of these instruments can help you become an algebra expert in very little time.
