When you have more than one operation in a math problem, you must solve it following the correct ORDER OF OPERATIONS:
  • First, copy the problem EXACTLY.
  • Then go through each level of operations (Please Excuse My Dear Aunt Sally).
  • Do the operations within each level from left-to-right.
  • Write the answer directly below the operation sign.
  • Bring down the other numbers (be careful not to re-use any).
  • Continue until all operations are completed.
