Are you someone who thinks your mind is quick and clear when it comes to math? For many people, this area of knowledge remains a great challenge, while others consider it to be their strong point. If you want to take the test of the 9, try to solve the logical reasoning test mathematician below.

Many teachers claim that a good part of solving a math question consists of interpreting the text. Therefore, it is very important to know what needs to be resolved before trying to do it.
So, look at the image above and pay close attention to what the question proposes as an answer. In this case, note that there is a very simple equation that only involves multiplication and subtraction.
However, also notice that the result does not match the answer to the equation, does it? Therefore, your big challenge here will be precisely to fix the equation so that the result is consistent.
To do so, you'll only need to move one of the matchsticks that are used to build both the numbers and the signs. In that case, you can move any toothpick except the equals sign at the end of the question and the number four in the result.
However, be careful, because you will need to solve the question in just forty seconds!
Ready? Good luck!
What's the result?
Tests like this are very difficult, since in addition to basic knowledge in mathematics, you also need to pay attention to the logical question of the question.
So, instead of giving up from here, try training new similar tests so that your mind is more capable of dealing with these challenges.
In this case, the correct answer is 8+2 – 6 = 4! This means that there was a change in the last digit before the equal sign, as well as in the first digit.
More precisely, we move a toothpick from the last digit, which was an eight, so that it becomes a six, and we add the toothpick we removed from the first digit to make an eight. Check the image below:
