This problem looks simple at first glance, but it’s designed to catch people who rush. The expression 15 ÷ 5 × 3 + 1 tests whether you remember one key rule in math—the order of operations.
Many people make the mistake of solving from left to right without thinking carefully. But the correct approach is to handle division and multiplication first, from left to right, before moving to addition.
15 ÷ 5 × 3 + 1
= 3 × 3 + 1
= 9 + 1
= 10
Start with 15 ÷ 5 = 3, then multiply 3 × 3 = 9, and finally add +1 to get 10.
What makes puzzles like this go viral is how easily they expose quick thinking mistakes. It’s not about complexity—it’s about attention. Even basic math can trip people up when they move too fast.
So the real question is… did you get 10, or did it fool you?
