Can You Solve This Math Riddle in Your Head Without Using Pen and Paper? Only a Few People Can

At first glance, this math puzzle seems extremely simple.

The numbers are basic.

The equation is short.

And most people feel confident enough to answer it in just a few seconds.

But that confidence is exactly what makes this riddle so deceptive.

Here’s the challenge:

90 − 10 ÷ 2 + 8 = ?

Try to solve it in your head before checking the answer.

For illustrative purposes only

The Common Mistake
Many people rush and calculate from left to right.

They think:

90 − 10 = 80
80 ÷ 2 = 40
40 + 8 = 48

So they conclude:

48

But that answer is incorrect.

The issue isn’t with the math itself.

The mistake comes from ignoring the order of operations.

Remember the Rule
In math, you don’t always solve expressions from left to right.

You must follow the correct order of operations.

Division and multiplication always come before addition and subtraction.
