This short math puzzle is easy to get wrong if you ignore the order of operations:
10 + 10 × 0 + 2 = ?
Answer: 12.
Multiplication comes before addition, so calculate 10 × 0 first. That equals 0.
The equation then becomes 10 + 0 + 2, which equals 12.
The common mistake is to work strictly from left to right. But standard arithmetic rules require multiplication and division to be completed before addition and subtraction unless parentheses change the order.
So the correct final answer is 12.
