Study Tips - Algebraic Problems

Algebraic Problems

Algebraic problems become easy to solve if a simple system is used and followed. In order to solve the algebraic problem, you need to process functions in a certain order to arrive at the right answer. The functions that need to be in order are addition, subtraction, multiplication and division.
A simple acronym has been developed to help students solve algebraic problems. The acronym is as follows: P.E.M.D.A.S. This stands for the following: Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
The first function to perform in an algebraic problem is to solve the operations listed in the parenthesis. Next settle the exponents. The next process is multiplication and division. You need to work from left to right. The last function is addition and subtraction. You need to work from left to right with these functions also. Always be sure to work from left to right.

Remember that you are working to get one answer on one side of an equal sign. All of the functions work toward this point. Derivative word problems are easily solved by going through the text and extracting the relevant numeric information. The purpose of finding the derivative in a word problem is so you will know the slope of the line on a graph, the point of inflection or the rate of change of the graph. Isolate out the equation in a word problem to get the derivative.
