A difficult exercise, that shows your intellect

This puzzle drove many Japanese, including scientists, crazy.

According to statistics, only 60% of people born after 1990 are able to solve this equation. At the same time, 30 years ago, 90% of 20-year-olds were able to do this! Are we dumb?

Try it too!

Well, does it work? There’s an answer? You can scroll and read the correct one.

Correct answer: 1.

Explanation:

Many begin to solve the equation incorrectly. The hardest part here is 1/3.

Here is the WRONG sequence:

9 – 3 ÷ 1/3 + 1 =

= 9 − 3/1/3 + 1 =

= 9 − 3/3 + 1 =

= 9 – 1 + 1 =

= 9

However, the first line breaks the rules.

Here is the RIGHT solution:

9 – 3 ÷ 1/3 + 1 =

= 9 – 3 ÷ (1/3) + 1 =

= 9 – 3 × 3 + 1 =

= 9 – 9 + 1 =

= 1
