Answer 1

Dear Irmak,

I'm pretty good at mathematics, but there's a little bit I don't understand about the way you typed these. It's been a while since I've been in class, though, like 20 years. :)

Thanks for the explanation. I guess I do need more detailed explanation. :) Sorry that I wasn't able to help more.

Answer 2

I don't understand the signs either. Can you tell what do they mean?
