Are you among the 20%

This problem is relatively harmful to the brain, but it is extremely easy to think of!

A little fun! Today, invite you to enjoy a problem that is causing netizens "crazy headaches" because of its "brain damage".

It is a problem of simulated addition . At first glance, the problem seemed to be very simple, but it made 80% of people asked to solve the problem.

This is an extremely interesting problem. Although there is only one answer, it has a lot of logic to go to that answer.

Do you have 20% of people who solve this problem in 5s?

Let's see the answer:

With this kind of problem of simulated simulations like this, we will need to have a logical arrangement thinking , using 3 expressions in the lesson to get the right result.

With such a way of thinking, this problem will have two solutions.

First, we use horizontal row logic.

Call 3 expressions respectively (1), (2), and (3). In expression (1), we notice, 5 = 4 - 2 + 3. This is also true for 2 longer expressions

re: 10 = 8 - 4 + 6; 2 = 3 - 2 + 1.

Applying that principle, how much do you calculate the last expression?

Or we can apply vertical row logic.

Notice that the expression (2) = (1) x2 = 5x2 = 10. Similarly, the expression (4) = (3) x2 = 2x2 = 4.

Answer

6 + 4 + 2 = 4

Do you have any logic? If yes, share it together!
