Students, got the algebra blues? Do you often get more than answers to the equation?
Take time to memorize this sentence: Please Excuse My Dear Aunt Sally.
When tackling an equation, the first order of business is to solve any part that is enclosed by parentheses, which the "P" stands for. The next order of business is to solve any parts which have exponents, which the "E" stands for. Next, do the part which calls for multiplication. Then solve the parts which call for division. Then work on the parts requiring addition and subtraction. So, please remember, "Please Excuse My Dear Aunt Sally"
