Can You Solve This Tricky Middle School Math Problem …Most People Get It Wrong
Think your basic math skills are still sharp? This deceptively simple arithmetic challenge has been circulating online—and surprisingly, a lot of people are getting it wrong.
While puzzles like Sudoku and crosswords are classic brain workouts, there’s something especially fun about revisiting old-school math problems. They look easy, feel familiar, and yet somehow manage to trip us up.
Maybe it’s because these problems take us back to middle school, where rules like the order of operations were drilled into us—then quietly forgotten over time.
So let’s put your memory to the test.
The Challenge
Without using a calculator, can you solve this arithmetic problem correctly?
You’re given one equation and four possible answers. At first glance, it seems straightforward—but don’t rush. Many people do… and that’s where they go wrong.

The Correct Answer
✅ Answer B: 12
Why Is 12 the Right Answer?
The key lies in remembering a rule most of us learned years ago: the order of operations.
As taught in school, multiplication and division must be performed before addition and subtraction.
So instead of working through the equation from left to right, you first solve the multiplication:
3 × 3 = 9
Once that’s done, you complete the remaining steps, which leads you to the final answer: 12
Why So Many People Get It Wrong
The mistake usually comes from ignoring—or forgetting—the order of operations and simply solving the equation in sequence. It’s an easy trap to fall into, especially when the problem looks simple.
But that’s exactly what makes these puzzles so entertaining: they challenge not just your math skills, but your attention to detail.
Final Thought
Problems like this are a great reminder that sometimes the simplest questions deserve a second look. A little patience—and a quick trip down memory lane—can make all the difference.
