Answer 1

\(\Huge\mathsf{Hai!}\)

Answer 2

So I was going to explain it.. but you could just look at this tutorial :3 http://openstudy.com/users/AccessDenied#/updates/4fa5b375e4b029e9dc35a2cf

To do what I did you do \Huge\mathsf{Hai!} and put inside of ∖(⋯∖)
You can also do colours with \color{teal}
\(\Huge\color{teal}{Hai!}\)
It defaults to a squiggly italic font, so that's why I do /mathsf :P
