When the OP is taking his/her test, will you be there to give him/her the answers?

We don't do homework on this site. We will help, but you have to put in the effort. Show us how you tried to solve it, the answer you came up with, and we can tell you if you're doing it right. If you aren't, we can help steer you in the right direction. But we will not give you the answer. You have to do the work, it's your homework for a reason.

Do you know how haze got the answer, tikachan18?
