# Only a person with high IQ can solve this calculation Logical challenges are known to everyone, some of which are shared among like-minded users on the Internet and contribute to creating a viral post. That’s what happens with challenges like the one we bring you today, which lets you test your wits and instincts at home.

Easy isn’t it? Stay focused and challenge your friends or co-workers with these numbers puzzle that you don’t understand. We warn you: only a few people can solve this puzzle, so don’t be discouraged if you can’t solve it.

## A Mathematician’s Brain: A Specific Brain?

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

To investigate this possibility, a study sought to determine whether a person’s math skills were related to the concentrations of two key neurotransmitters involved in learning. Cognitive neuroscientists at the University of Oxford in England examined levels of GABA and glutamate in the brain to see if these neurotransmitters could predict future math skills. GABA and glutamate are two naturally occurring amino acids that play complementary roles: the first inhibits or slows the activity of neurons or nerve cells in the brain, and the second makes them more active. Their levels vary throughout life.

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

Most of the users who try to solve it do not give the correct answer. Those with an IQ above 140,

As you can see from the attached image at the top of the page, today’s challenges include serial relationships that seem crazy at first glance.

Apparently, the logic is in the minds of the puzzle creators, and it’s 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. Thus we get:
1 + 4 = 5
5 + (2 + 5) = 12
12 + (3 + 6) = 21
By this method, we end up with 21 + (8 + 11) = 40? = 40

## Method number 2

In this second scientific method, it is recommended that a multiplication be added to the process. More precisely, in addition to addition, it is necessary to multiply the second digit by the first digit. Thus we get:
1 + (4 x 1) = 5
2 + (5×2) = 12
3 + (6×3) = 21

By this method, we end up with: 8 + (11 x 8) = 96 So? = 96

It may be too simple to have two correct answers. According to Randall Jones, there is only one. So which one is right?

## 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

Calculating the last operation, we end up with 77 + (8 + 11) = 96, 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

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

Hence: If both methods are considered correct, the only correct answer is => 96
