Operations are the actions taken to solve math problems: addition, subtraction, multiplication, division, grouping (placing values in parentheses), and exponentiation (multiplying the same number to itself a certain number of times). Order of Operations was developed to make sure operations in a problem are completed in a particular order to achieve the correct result.
The Order of Operations (PEMDAS)
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
Multiplication does not outrank Division, and Addition does not outrank Subtraction. Instead, the order is determined by what operation appears first going from left to right.
