At first glance, this math problem looks incredibly easy—but it’s actually tricking thousands of people online.
The expression is: 9 − 9 × 9 + 1.
Most people rush and get the wrong answer because they forget one key rule: order of operations.
Before you do any adding or subtracting, you must handle multiplication first. That means you solve 9 × 9 = 81 before anything else.
Now the equation becomes: 9 − 81 + 1.
From here, go left to right:
9 − 81 = -72
-72 + 1 = -71
And that’s the correct answer.
Simple, right? But only if you slow down and follow the rules. These puzzles are designed to catch people who rush through calculations without thinking carefully.
Did you get it right on your first try—or did it trick you?
