At first glance, this looks like basic math. Something you’d expect anyone to solve in seconds.

5 + 2 × 2 − 15 = ?

Easy, right? That’s exactly why so many people get it wrong.

The brain loves shortcuts. When you see numbers like this, there’s a strong temptation to just go left to right without thinking too much. And that’s where the mistake happens.

This isn’t about intelligence—it’s about remembering one simple rule most people forget under pressure: the order of operations.

Multiplication always comes before addition and subtraction. No exceptions.

So instead of rushing, slow it down for a second. Look at the expression carefully.

The key step is hidden in the middle, and once you handle that correctly, everything else falls into place almost instantly.

It’s one of those problems where the answer feels too simple once you see it… but surprisingly tricky until you do.

Take a moment. Solve it properly.

Answer:

First do multiplication:

2 × 2 = 4

Now the equation becomes:

5 + 4 − 15

5 + 4 = 9

9 − 15 = -6

👉 Final Answer: -6
