This quick math puzzle asks you to solve 20 + 5 × 0 + 5 without using a calculator.
The correct answer is 25.
The key is the standard order of operations. Multiplication comes before addition, so first calculate 5 × 0. That equals 0.
The expression then becomes 20 + 0 + 5. Adding those numbers gives 25.
So the full calculation is: 20 + (5 × 0) + 5 = 25.
Many people get a different answer because they instinctively calculate from left to right. But multiplication must be completed first unless parentheses tell you to do something different.
