http://www.coolmath.com/prealgebra/06-order-of-operations/05-order-of-operations-parenthesis-PEMDAS-01.htmPEMDAS is the way to solve equations in the right order. You can also refer to it as Please Excuse My Dear Aunt Sally to help you remember. You always solve from left to right following PEMDAS.
Lets start with P, this means parenthesis goes first: ( ), { }, [ ]. Then, second in operation goes E, meaning exponents plus root. Then in order5 of importance is Multiplication and Division that are equal in priority (solve from left to right in importance). These are M and D: /, *, x. The last to letters stand for Addition and Subtraction that also have the same priority. Examples of A and S: +, -.
This system helped us during this unit a lot. I hope it helps you too.

Pauuuuu!

veryyy nicee !
