At first glance, this math puzzle looks so easy that almost anyone could solve it in seconds. There are no complicated equations, no fractions, and no advanced mathematical formulas. Just four numbers and three familiar operations. Yet this simple challenge has sparked debates because people keep arriving at different answers.

The equation is 90 ÷ 10 + 7 × 2 = ?

Above the puzzle, a bold statement reads, “The Answer Is NOT 18!” But is that statement correct, or is it simply designed to make people second-guess themselves? Some people immediately start calculating from left to right, while others remember a rule they learned years ago in school.

The interesting part is that even people who feel confident about their mathematical abilities can make mistakes when solving expressions like this too quickly. One small misunderstanding can completely change the final result.

Before revealing the solution, try solving the equation without using a calculator. Pay close attention to which operations should come first.
