1: Hello guys! How are you?
2: I had really awful day. I got 2 in Maths and my mother didn't allow me to play computer now.
3: I had the same situation last Monday. Maths is a terrible subject
1: Oh, but I like Maths! My father's a mathematician, and I think I'll be a mathematician in future too.
2: I just can't understand it, that's why I hate it.
1: Oh, Maths is very interesting and it is quite easy!
3: Maybe you'll explain it to us?
1: OK, let's go!
