Today’s Objective To be able to solve algebra problems in the correct order.

Order of Operations P = Parenthesis E = Exponent M = Multiply PEMDAS P = Parenthesis E = Exponent M = Multiply D = Divide A = Add S = Subtract PEMDAS

Order of Operations There are 4 levels of the Order of Operations. 1.) Parenthesis 2.) Exponents 3.)Multiply & Divide 4.)Add & Subtract

Parenthesis PEMDAS Exponent Multiply Divide Add Subtract
