At first glance, this math puzzle seems incredibly easy. That’s exactly why it tricks so many people! Most people see the expression and immediately start calculating from left to right without thinking about the correct order of operations.
The problem is:
20 ÷ 4 – 3 × 2 + 7 = ?
Some people answered 11, while others confidently chose 180. But are either of them correct?
The key to solving this puzzle is remembering the basic rule of mathematics: Division and multiplication always come before addition and subtraction. When division and multiplication appear together, solve them from left to right. After that, complete the addition and subtraction, also from left to right.
Let’s solve it step by step:
- 20 ÷ 4 = 5
- 3 × 2 = 6
Now the equation becomes:
5 – 6 + 7
Continue solving from left to right:
- 5 – 6 = -1
- -1 + 7 = 6
✅ The Correct Answer Is: 6
That means neither 11 nor 180 is correct.
This puzzle is a great reminder that even simple-looking questions can fool us if we rush. Our brains often want to calculate everything from left to right, but math has its own rules. Taking just a few extra seconds to follow the proper order of operations can completely change the result.
