Most AV math formulas use only the four common operators: add, subtract, multiply, and divide. However, some formulas require a solid foundation in the order of operations. The order of operations helps you correctly solve formulas by prioritizing which part of the formula to solve first. It is a way to rank the order in which you work your way through a formula. Take a moment to review and test your knowledge of applying the order of operations.

This is the order of operations:

  1. Any numbers within a pair of parenthesis or brackets
  2. Any exponents, indices, or orders
  3. Any multiplication or division
  4. Any addition or subtraction

If there are multiple operations with the same priority, then proceed from left to right:

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

The order of operations can be remembered by using one of these acronym: PEMDAS, BEMDAS, BIDMAS, or BODMAS.

Remember: If the priority of operations is the same, begin solving from left to right.
