Perhaps with some of the set theory stuff, like unions intersections and the like, that would be most useful.

And the null set, that was a pain to figure out. Just set theory in general I think would be nice.

\begin{array}{ccc}\in & & \backslash \text{in} \\ \\

\overline{A \cap B} & & \backslash\text{overline}\{A\text{ cap }B\}  \\ \\

\sim A & & \backslash\text{sim }A\end{array}



I use \sim\!\!A to remove that space: .\sim\!\!A

. . \text{I also use that trick for }\sin^2x\!: . \sin^2\!x . .\Rightarrow\quad \sin^2\!x
