This document discusses order of operations in math and explains that multiplication and division must be performed before addition and subtraction to get the correct answer. It provides examples like 3 + 6 x 4, where following the order of operations (BEDMAS) gives the answer of 27 rather than 9 x 4 = 36. The document also lists several common mnemonics like PEMDAS, PLEASE EXCUSE MY DEAR AUNT SALLY, and BIG ELEPHANTS DESTROY MICE AND SNAILS that remind students of the proper order of operations.
