\section*{Problem 1}
\newpage

\section*{Problem 2.1}
If a problem has multiple parts, please put a \verb!\newpage! between each subpart.  For example, like this.
\newpage

\section*{Problem 2.2}
And like this.
\newpage

\section*{Problem 2.3}
And like this.
\newpage

\section*{Problem 3}
Similarly, if a problem (or a subpart) ends up taking more than 1 page, please put (Continued) in the \verb!\section*! for that page.  You can also use \verb!\newpage! to choose where (in your work) the current page ends and where the next page begins.
\newpage

\section*{Problem 3 (Continued)}
Like this.

\section*{Example Proof}
\noindent\textbf{Want to Prove:} $x+y=x+z \ni x,y,z \in \mathcal{Z} \implies y=z$.\vspace{0.5em}\\
$\begin{aligned}
x+y &= x + z\\
(-x)+(x+y) &= (-x)+(x+z)\\
((-x)+x)+y&=((-x)+x)+z\\
0+y &= 0+z\\
y &= z \qed
\end{aligned}$
\text{ }\vspace{2em}\\
\textbf{\LaTeX\ Pro Tip}: They key to the \texttt{aligned} environment is to use the \& operator as what everything aligns to.  Note that, above, we always have it as \texttt{\&=}, meaning that each line has the \texttt{=} sign aligned to the same spot.  This makes the proof much easier to read.\vspace{1em}\\
\textbf{Math Pro Tip}: The $\qed$ symbol, called \href{https://en.wikipedia.org/wiki/Q.E.D.}{Q.E.D.}, is often used to signal the end of a proof.
\newpage

\section*{Example Math Work}
$\begin{aligned}
(1 + 2 + 3 + 4 + 5) \cdot 1000 &= (3+3+4+5) \cdot 1000\\
&= (6+4+5) \cdot 1000\\
&= (10+5) \cdot 1000\\
&= (15) \cdot 1000\\
1 + 2 + 3 + 4 + 5 &= \doubleunderline{15000}\\
\end{aligned}$
\text{ }\vspace{2em}\\
\textbf{\LaTeX\ Pro Tip}: Feel free to use the \verb!\doubleunderline! command to double-underline your final answer, which can make your work easier to read.
\newpage

\section*{Example Table}
\textbf{\LaTeX\ Pro Tip}: Use \href{https://tablesgenerator.com/}{tablesgenerator.com} to save \textit{a lot} of time when making tables.  You can even copy/paste from Excel or import a CSV!
\begin{table}[H]
\begin{tabular}{|c|c|c|c|c|}
\hline
\rowcolor[HTML]{333333} 
{\color[HTML]{FFFFFF} \textbf{Column 1}} &
  {\color[HTML]{FFFFFF} \textbf{Column 2}} &
  {\color[HTML]{FFFFFF} \textbf{Column 3}} &
  {\color[HTML]{FFFFFF} \textbf{Column 4}} &
  {\color[HTML]{FFFFFF} \textbf{Column 5}} \\ \hline

 &  &  &  &  \\ \hline
 &  &  &  &  \\ \hline
\end{tabular}
\caption{Table Caption Here}
\end{table}
\newpage

\section*{Using an Uploaded Photo}
\textbf{\LaTeX\ Pro Tip}: Avoid using underscores in file names to make your life easier.  \href{https://tex.stackexchange.com/questions/58689/how-to-use-an-underscore-in-a-filename}{There are ways around this} but it's likely easier to just rename a file.

\textbf{\LaTeX\ Pro Tip}: To remove the image caption, comment out the \verb!\caption! line.

% To make this come out properly in landscape mode, do one of the following
% 1.
%  pdflatex latexsheet.tex
%
% 2.
%  latex latexsheet.tex
%  dvips -P pdf  -t landscape latexsheet.dvi
%  ps2pdf latexsheet.ps


% If you're reading this, be prepared for confusion.  Making this was
% a learning experience for me, and it shows.  Much of the placement
% was hacked in; if you make it better, let me know...


% 2008-04
% Changed page margin code to use the geometry package. Also added code for
% conditional page margins, depending on paper size. Thanks to Uwe Ziegenhagen
% for the suggestions.

% 2006-08
% Made changes based on suggestions from Gene Cooperman. <gene at ccs.neu.edu>


% To Do:
% \listoffigures \listoftables
% \setcounter{secnumdepth}{0}


% This sets page margins to .5 inch if using letter paper, and to 1cm
% if using A4 paper. (This probably isn't strictly necessary.)
% If using another size paper, use default 1cm margins.

The \textit{place} is a list valid placements for the body.  \texttt{t}=top,
\texttt{h}=here, \texttt{b}=bottom, \texttt{p}=separate page, \texttt{!}=place even if ugly.  Captions and label markers should be within the environment.

Tab stops can be set on ``invisible'' lines with \verb!\kill!

\section{Math mode}
For inline math, use \verb!\(...\)! or \verb!$...$!.
For displayed math, use \verb!\[...\]! or \verb!\begin{equation}!.

\subsection{Math-mode symbols}

% The ordering of these symbols is slightly odd.  This is because I had to put all the

% Otherwise, it wouldn't be possible to fit four columns of symbols here.
