Succeeding in Algebra
Algebra - what is it?
It is an area of mathematics that use alphabetic characters in replacement of numbers to derive results for a given situation. It is this abstraction that often scares many and shudders some. Algebra topics range by working through simple tasks such as factoring trinomials and eventually progressing on to finding the product of matrices. Most people start to learn 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 advanced topics. Firstly there are exponents. An exponent is the little 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 expressed as, 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, simply put, is the reversing of an power. The V beside 4 denote a radical expression which means, the square root of 4, which equals 2. The contrasting exponential equation is 2^2 which is read, 2 to the 2nd power, and 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 exponents and radicals aren’t enough, there is always 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!
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 discipline. The custom is to decide on a math tutor, but the up-to-date 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 guru in no time.
