What is Algebra?
Algebra is a broad part of mathematics that uses generalization by substituting letters for numbers. It is this generalization that often frightens many and shudders some. Algebra topics range by working through simple tasks such as factoring polynomials and eventually progressing on to finding the inverse of a matrix. In almost all cases, just as in any other maths associated class, students start off 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.
Oh no! It’s Exponents, Radicals and Graphing
There are numerous advanced themes. Firstly there are powers. An exponent is the small number placed as superscript to 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, x plus y to the third power. In working with powers you can add, subtract, multiple or divide them. If you pick up the basics, 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 undoing of an exponent. Radical expressions are shown by the symbolic representation “V” and when placed next to 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. Moreover, powers can be added, subtracted, multiplied or divided by radicals. Radicals can be switched into exponents and exponents 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 work 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? Once you master graphing lines, a whole world of circles, parabolas and hyperbolas awaits you!
Want 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 subject area. The custom is to settle for a math tutor, but the cutting-edge 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 tools can assist you become an algebra expert in very little time.
