Only a person with a high IQ will be able to solve this calculation

Logical challenges are known to everyone, some of them are shared on the web between users with the same passions and contribute to making a viral post. This is what happens with challenges like the one we bring to you today, which allows you to test your intelligence and your intuition at home.

Easy isn’t it? Concentrate and try to challenge your friends or colleagues with the riddle of these numbers that seem incomprehensible to you. We warn you: only a few people are able to solve this riddle, so don’t be discouraged if you can’t solve it.

A mathematician’s brain: a specific brain?

You may know it, but the ability to understand mathematics is studied by science. Researchers have indeed wondered if math teachers and arithmetic geniuses could be born with a biological advantage?

To explore this possibility, a study sought to determine whether a person’s math skills were associated with concentrations of two key neurotransmitters involved in learning. Cognitive neuroscientists from the University of Oxford in the UK examined levels of GABA and glutamate in the brain to see if these neurotransmitters could predict future math abilities. GABA and glutamate are two natural amino acids that play complementary roles: the first inhibits or reduces the activity of neurons or nerve cells in the brain, while the second makes them more active. Their levels fluctuate throughout life.

We have also attached the solution but don’t cheat, only read it after trying to answer!

Most users who try to solve it do not give the correct answer. And those who did had an IQ over 140,

What is the answer :

As you can see from the attached image at the top of the page, today’s challenges include a series of ties that, at first glance, seem insane.

Obviously, the logic is there in the minds of the creators of the puzzle and it’s really up to you to figure it out!

Method number 1

The first method is to add the result of the previous operation to the next one. We thus obtain:
1 + 4 = 5
5 + (2 + 5) = 12
12 + (3 + 6) = 21
With this method, we then end up with: 21 + (8 + 11) = 40 so? = 40

Method number 2

In this second more scientific method, it is suggested that a multiplication should be added to the operation. More exactly that it is necessary, in addition to the addition, to multiply the second digit by the first. We thus obtain:
1 + (4 x 1) = 5
2 + (5×2) = 12
3 + (6×3) = 21

With this method, we then end up with: 8 + (11 x 8) = 96 so? = 96

It could quite simply be that there are two correct answers. Except that according to Randall Jones, there is only one. So which is the right one?

If we use method 1

1 + 4 = 5
5 + (2 + 5) = 12
12 + (3 + 6) = 21
21 + (4 + 7) = 32
32 + (5 + 8) = 45
45 + (6 + 9) = 60
60 + (7 + 10) = 77

If we calculate the last operation, we end up with: 77 + (8 + 11) = 96 and not 40 as at the beginning.

If we use method 2

1 + (4 x 1) = 5
2 + (5×2) = 12
3 + (6×3) = 21
4 + (7×4) = 32
5 + (8 x 5) = 45
6 + (9 x 6) = 60
7 + (10 x 7) = 77

The last operation, we find: 8 + (11 x 8) = 96

So: if both methods can be considered correct, The only correct answer is => 96
