Riddle about NumbersThis time Geniusbeauty is posting a mathematical brain game. Try to solve this riddle. Place the numbers from 1 to 9 into a 3×3 square so, that the sum of the numbers in each table, raw and diagonal is the same. Please, if you want to find the solution yourself, do not look at the comments of this post, because someone could have already written it there. Good luck!

You will find the solution in the next brain game. You are always welcome to ask questions about the task, in case something is not clear. But sorry, I will not answer leading questions.

The answer to the previous brain game is: turn off all the switches. Wait until the lamps cool. After it turn on two switches and then turn off one of them. If when you come to the closet, the lamp shines, than the needed switch is the switched on one. In case the lamp is off, when you come to the closet, then touch the lamp and check if it is warm or cold. If it is warm, then the needed switch is that one, which was just turned off. If the lamp is cold, then the third one, which was turned off all the time. Congratulations to those, who solved it!
