Problem:
3 + 3 × 3 − 3 + 3 = ?
It looks simple, but many get it wrong by adding in the wrong order.
Follow order of operations (multiplication first):
3 × 3 = 9
So it becomes:
3 + 9 − 3 + 3
Now left to right:
3 + 9 = 12
12 − 3 = 9
9 + 3 = 12
✅ Correct answer: 12
Most people get 18 by adding everything first, but multiplication always comes before addition and subtraction.
