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.
