The document provides a mnemonic device called "PEMDAS" to help remember the order of operations when solving equations: P for Parentheses, E for Exponents, M for Multiplication, D for Division, A for Addition, and S for Subtraction. It explains that operations inside parentheses should be performed first, followed by exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right. Several examples are given applying this order of operations when solving equations to help the reader understand which step comes first.
