Answer 2

```latex
\(\begin{cases}
2x+3 & {if~x<0} \\ /*This is where the first second and every
other eq would go, separate by line using 2 backslashes*/
1 & {if~x=2} \\

x^2 & {if~x>2}
\end{cases}\)```

That is amazing

Answer 4

unfortunately it doesn't work with the latex I'm using on another site.
I'll just post it on this site and screenshot it.

0 & {if~a_{nn} \neq 0} \\
1 & {if~a_{nn}=0}
