=**Welcome to the Order of Operations Unit**= Order of operations is an expression that has more than one operation, and you must know which operation to do first. To make sure everyone gets the same answer, we use the order of operations. The order of operations is: 1. Perform operations in parentheses. 2. Find the values of numbers with exponents. 3. Multiply or divide from left to right as ordered in the problem (ALWAYS DIVIDE BEFORE MULTIPLYING). 4. Add or subtract from left to right as ordered in the problem. A good trick for remembering rules is PEMDAS-Please Excuse My Dear Aunt Sally P-parentheses E-exponents M-multiply D-divide A-add S-subtract
