The Correct Order when Solving Combined Operations

The rules for the order of operations in an addition and subtraction exercise are quite simple.

In exercises with combined operations in which there are also multiplications and divisions, the order of operations is as follows:

  1. Parentheses
  2. Powers and roots
  3. Multiplications and divisions
  4. Addition and subtraction
