They’re real **challenges** for intellectuals who want to keep their minds active, while eliminating fatigue and stress.

**Puzzles** mathematics are real hobbies, because if the scenarios are in equation form, it’s important to apply your skills to solve the problems.

The image of equation and calculation is an outward facade, but you need to think critically based on mathematical principles and analyze data to arrive at the right result.

## IQ test: 1 + 1 = 5, 6 + 6 = 180, 7 + 7 = ?

This image shows a simple equation to be solved, but the results don’t necessarily correspond to the logic of the calculations.** The aim is to decipher the pattern, taking into account the similarities in the first two equations.**

You also need to reason logically, think quickly and use your analytical skills in a very short space of time.

To achieve this, it’s important to observe the details of each element and be meticulous about each one. Those who are used to this kind of** challenge** will quickly find the corresponding solution.

## IQ test: the answer

Practising this kind of mathematical challenge stimulates your brain, helps you to achieve a high level of intelligence and guarantees good moral health. This ability is essential for all your future projects.

By developing your cognitive skills, you can improve various aspects of your life and solve problems quickly and easily. IQ tests also help you to develop the mental capacity you need for your career or studies.

To find the right answer to this mathematical riddle, you have to look at it from different angles and find the right solving technique among the long lists.

You need to gather the data conditions of the equations and determine the code that might lead you to the right answer. Once you’ve mastered the basics of mathematics and logic, not forgetting your sense of observation and attention to detail, it’s time to answer the equation.

## Solution

This equation is a real challenge, requiring you to work out each digit and calculation sign step by step. Here, the addition sign is converted to multiplication.

In the first equation, 1 + 1 = 5, 1 is multiplied by 1 to give 1. The latter is multiplied by 5, giving 5. In short, 1 x 1 = 1 x 5 = 5.

For the second equation, 6 + 6 = 180, 6 is multiplied by 6, giving 36 multiplied by 5, which gives 180, i.e. 6 x 6 = 36 x 5 = 180.

** Finally, the last equation, 7 + 7 = ? 7 is multiplied by 7 to give 49, which is multiplied by 5 to give 245.**
