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
