% The following two environments (theorem, proof) are
% where you will enter the statement and proof of your
% first problem for this assignment.
%
% In the theorem environment, you can replace the word
% "theorem" in the \begin and \end commands with
% "exercise", "problem", "lemma", etc., depending on
% what you are submitting. Replace the "x.yz" with the
% appropriate number for your problem.
%
% If your problem does not involve a formal proof, you
% can change the word "proof" in the \begin and \end
% commands with "solution".
% -----------------------------------------------------
\begin{theorem}{x.yz}
Replace this text with the statement of the theorem you are proving.
\end{theorem}
\begin{proof}
Replace this text with the details of your proof or solution.
\end{proof}
% -----------------------------------------------------
% Second problem
% -----------------------------------------------------
\vspace{0.25in} % This just adds some space between problems 1 and 2.
\begin{theorem}{x.yz}
Replace this text with the statement of the theorem you are proving.
\end{theorem}
\begin{proof}
Replace this text with the details of your proof or solution.
\end{proof}

% Third problem
% -----------------------------------------------------
\vspace{0.25in} % This adds some space between problems 2 and 3.
\begin{theorem}{x.yz}
Replace this text with the statement of the theorem you are proving.
\end{theorem}
\begin{proof}
Replace this text with the details of your proof or solution.
