Order of Operation
Even though your calculator may know some of the rules below and do it correctly, you need
to know the rules yourself so that you enter the numbers in the right order.
This is the order:
1. Do operations inside the parentheses first.
2. Do logarithms, and powers next.
3. Do multiplication and divisions next.
4. Do addition and subtraction last.
1. Do this without a calculator:
4 + 9 ÷ 3 − 2 x 3 + (3 + 1) x 4 = _______17____________________
