This game is very helpful for children to learn basic math. 

The background story of this game is that your friend left his seven notebooks at school. 

The protagonist needs to go back to school and retrieve the seven notebooks. 

But their teacher, Bardi, likes to let them answer questions. 

Every time the protagonist finds a notebook, he needs to answer three questions. 

Of course, each question answered correctly will receive a coin reward. 

But if the question is answered wrong, the protagonists will be chased by their teacher Bardi. 

The bad news is that when you are running for your life, you may be stopped by the school bully. 

Sometimes there may be a girl skipping rope. 

She'll let you jump rope with her ten times. 

Even if it takes time, you have to do it. 

Of course, there are ways to get your teacher to slow down. 

For example, you can buy grade B soda from the vending machine. 

By throwing this soda at your teacher, you can slow her down and quell her anger. 

You'd better use soda at the end of the corridor. 

Another effective way is to use the mobile phone, because it will interfere with the teacher's listening. 

But this method is not free. 

You need to pay a coin for this. 

You can also try to cut the girl's rope into parts. 

In this way, she won't ask you to jump rope with her, which can also save you time.
