This quick math puzzle looks very simple, but the multiplication by zero can easily cause a wrong answer if you rush.

The expression is:

1 + 7 × 0 + 2

To solve it correctly, follow the standard order of operations. Multiplication comes before addition.

Start with:

7 × 0 = 0

Now the expression becomes:

1 + 0 + 2

Then complete the remaining addition:

1 + 2 = 3

So the correct answer is:

3

A common mistake is to calculate the equation from left to right and add 1 + 7 first. Another mistake is to assume the whole expression becomes zero because it contains ×0. But only the 7 is being multiplied by zero.

That small detail is what makes these short math puzzles so easy to misread.

Answer: 3.
