This quick math puzzle looks simple, but the multiplication by zero can easily catch anyone who rushes.
The expression is:
2 + 3 × 0 + 7
To solve it correctly, follow the standard order of operations. Multiplication must be completed before addition.
Start with:
3 × 0 = 0
Now the expression becomes:
2 + 0 + 7
Then complete the remaining addition:
2 + 7 = 9
One common mistake is to work from left to right and add 2 + 3 before doing the multiplication. Another is to assume the entire expression becomes zero because of the ×0. But only the 3 is being multiplied by zero.
So the correct answer is:
9
It is a very short equation, but that small ×0 is enough to make people second-guess themselves.
Answer: 9.
Did you get 9 on your first try?
