This quick math puzzle asks you to solve 20 + 20 × 0 + 5. The numbers are simple, but the order of operations is what matters.
The correct answer is 25.
Multiplication must be done before addition. Start with 20 × 0, which equals 0. The expression then becomes 20 + 0 + 5. Add the remaining numbers and you get 25.
So the full calculation is: 20 + (20 × 0) + 5 = 20 + 0 + 5 = 25.
These puzzles often cause debate because people instinctively work from left to right. But standard arithmetic rules require multiplication and division to be completed before addition and subtraction unless parentheses tell you otherwise.
