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) Perform exponents next from left to right. 3) Perform multiplication and division from left to right. 4) Perform addition and subtraction from left to right. Some example problems are worked out step-by-step to demonstrate how to follow PEMDAS.

2. The Order of Operations
tells us how to do a math
problem with more than one
operation, in the correct
order.
