 	To put a title on a simple homework assignment, you only need lines \texttt{31}-\texttt{37} in the code (\texttt{LaTeX\_for\_Undergraduates.tex}) instead of an entire \texttt{titlepage}, but you don't necessarily have to use this method. You can put the title, your name, and the date on the paper however you'd like. \\
 
 	As you read this, use the keyboard shortcut Ctrl + F to search for specific things in the code so that you can compare the code precisely to what's being printed.

 	When nesting block delimiters inside of each other, it is often beneficial to use an abbreviation of \verb$\boldsymbol$ to bold the outer delimiters. For instance, $g^{-1}\bs((c,d)\bs)$ is a little better than $g^{-1}((c,d))$.
