The document explains the order of operations (PEMDAS) for solving math problems with multiple operations: 1) Perform operations inside parentheses first, from left to right. 2) Evaluate exponents next, from left to right. 3) Multiply and divide from left to right. 4) Add and subtract from left to right. It provides the mnemonic "Please Excuse My Dear Aunt Sally" to remember the order: Parentheses, Exponents, Multiply, Divide, Add, Subtract. Several example problems demonstrate applying the order of operations to solve multi-step equations.
