This quick math puzzle has people giving different answers—but there’s only one correct solution.
The expression is:
10 − 10 ÷ 10 + 10
The trick is remembering the order of operations. Division always comes before addition and subtraction.
First, solve the division:
10 ÷ 10 = 1
Now the equation becomes:
10 − 1 + 10
Work from left to right:
10 − 1 = 9
9 + 10 = 19
✅ The correct answer is **19**.
Many people mistakenly subtract first and end up with a different result. That’s exactly why puzzles like this spread so quickly online—they test whether you remember the proper order of operations rather than how fast you can calculate.
Did you get 19 on your first try?
