Richard and his buddy Thomas came together to play games. Their plan was to play games at first, and then to study lesson. They ran to the garden and decided to play their favourite game’ hide and seek’.

However, they were only two.

Suddenly Richard saw his sister sitting on the grass. He had an idea. He would invite her to their game.Thomas agreed to with him, too and they went next to Nancy to talk. 

Richard: Hi, my dear sister.

Thomas: Hi, Nancy

Nancy: Hi boys.

Richard: Hey Nan, would you like to play hide and seek with us?

Nancy thought a bit and shook of her head!

Nancy: No, I cant. I have to study for the exam my dear big bro.

Thomas shrugged his shoulders. While they were leaving her alone, suddenly Nancy shouted at them.

Nancy: Wait boys! I have a trouble with a question. I couldn’t solve it. Can you help me?

Thomas and Richard came back and sat beside Nancy . She gave them the book and showed the question .The question she couldn't solve was a Math question.

Thomas: OMG What is that?

Nancy: Yeah, it is too difficult. I tried all operations but i couldn't solve it.

Richard scratched his head as if he didn't know what to do. He was not so smart.

Richard: Really it is very difficult. And complicated!

Thomas: Let’s transform this question into a game. Imagine that we are knights who are fighting in a labyrinth with full of numbers. Moreover, there is only one way to go out. And this way is to solve the problem!

Meanwhile Thomas had an ide.,

Richard smiled and said: Good idea!

Richard´ Thomas and Nancy closed their eyes and just imagine...

And BOOM!

They were in labyrinth!

Each of them was a knight working on his own aiming to get out of the labyrinth. None of them succeeded, so that they decided to work together to beat the numbers and help Nancy.

They started to organize their work, and, on their way, they met a seven-headed dragon. He stopped them and said:

I will only let you go on if you tell me the value of x in the equation ‘x : (16-63:9) = 6’.

Children:

It is simple. x  : (16-7) = 6,

x  : 9 = 6, x = 6 * 9, so, x = 54.

As the children answered correctly, the dragon miraculously disappeared in a few minutes. The three friends continued their journey and finally they succeeded in coming to the exit road, defeating the numbers. 

Nancy: Thank you for helping me to sort out this problem, which made us a lot of troubles.

When they opened their eyes, they were back into the garden. And mmm strange thing: the equation the dragon gave them was the same Nancy couldn’t solve by the beginning.

This way, they transformed the difficult Math problem in a game, and solved it easily.

The next day, Nancy was very happy, because she got the best mark to her exam. Everyone was very happy for her success.

And so, they learned two lessons: firstly, they realized that they could learn by playing games, secondly, they understood the value of the friendship. As in the saying: “A friend in need is a friend indeed".
