The problem is:
3 + 3 × 3 − 3 + 3 = ?
At first, it may look very simple, but many people get the wrong answer because they solve it too quickly.
The correct way is to follow the order of operations.
First, solve the multiplication:
3 × 3 = 9
Now the problem becomes:
3 + 9 − 3 + 3
Next, solve from left to right:
3 + 9 = 12
12 − 3 = 9
9 + 3 = 12
So the correct answer is:
✅ 12
Many people choose 18 because they add the numbers first, but multiplication must always be done before addition and subtraction.
