nerd souhlasí, že pomůže populárnímu chlápkovi ve škole otevřít zadek

Hello! How are you? I need to talk to you about something important.

Hello, Joel. What happens? You seem worried.

Yes, I'm quite worried. It turns out that I have a lot of trouble understanding and completing the math homework.

And if I don't manage to pass it, I'm going to lose the subject.

Oh wow. That sounds complicated. In what part of the task are you having difficulties?
