Let’s Explore Algebra
It is an domain of mathematics that use alphabetic characters instead of numbers to derive results for a given situation. It is this generalization that often frightens many and shudders some. Algebra topics extend from working with fractions to factoring binomials all the way to finding the y-intercept. Most people get down to study 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.
Exponents and Radicals and Graphing Oh My!
There are many another higher level topics. First 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 exponent and refers the power to which that number is exponentiated. The above algebraic expression is read as, x plus y to the third power. While working with exponents you will often encounter exercises that require you to add, subtract, multiply and divide. 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 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 changed into powers and exponents back into radicals. If you find that powers 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. Does the line have 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 content. The tradition is to settle for a math tutor, but the modern 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 help you become an algebra guru in very little time.
