Can you solve this banal example for schoolchildren that turned out to be difficult for hundreds of people all over the Internet

Sometimes school exercises and questions are harder for children to answer. And the proof for that is this photo that appeared on the network, and caused so many questions. This simple task has become unsolvable for Twitter users. Readers of the actor’s page tried to solve an example that is intended for schoolchildren.

One commentator posted the problem and invited readers to solve it. The task was to add the numbers outside the brackets and subtract the numbers inside the brackets.

The example consisted of fairly simple numbers, but the difficulty lay in the order of operations: 2+5x(8–5).

This task has become unsolvable for many users, and they couldn’t believe it was for schoolchildren. The most relevant answer was “21”.

Decisive primes first added the numbers before the brackets, then subtracted in brackets, and the results were multiplied.

There were also many people saying that the answer is “17”. The example was solved as follows: first, the numbers in brackets were subtracted, and then the numbers were multiplied and added. And the second group of users turned out to be right, the correct answer to the problem is “17”.
