When performing more than one operation on an algebraic expression, you must use the different operations in a precise order. Grouping symbols, such as parentheses and brackets, can interrupt the order of operations. The order of operations is listed here:

  1. Powers or roots

  2. Multiplication or division

  3. Addition or subtraction

If an operation appears more than once in an expression, perform that operation from left to right.
