\title{Weekly Homework X}%replace X with the appropriate number
\author{Tony Stark\\ %replace with your name
Foundations of Mathematics} %if necessary, replace with your course title
\maketitle
\begin{theorem}{x.yz} %You can use theorem, exercise, problem, or question here. Modify x.yz to be whatever number you are proving
Delete this text and write theorem statement here.
\end{theorem}
\begin{proof}
Blah, blah, blah. Here is an example of the \texttt{align} environment:
%Note 1: The * tells LaTeX not to number the lines. If you remove the *, be sure to remove it below, too.
%Note 2: Inside the align environment, you do not want to use $-signs. The reason for this is that this is already a math environment. This is why we have to include \text{} around any text inside the align environment.
\begin{align*}
\sum_{i=1}^{k+1}i & = \left(\sum_{i=1}^{k}i\right) +(k+1)\\
& = \frac{k(k+1)}{2}+k+1 & (\text{by inductive hypothesis})\\
& = \frac{k(k+1)+2(k+1)}{2}\\
& = \frac{(k+1)(k+2)}{2}\\
& = \frac{(k+1)((k+1)+1)}{2}.
\end{align*}
\end{proof}
\begin{theorem}{x.yz}
Let $n\in \Z$. Then yada yada.
\end{theorem}
\begin{proof}
Blah, blah, blah. I'm so smart.
\end{proof}

Hi, thanks for code!
What else can be filled as replacement for \begin{proof}, like \begin{solution} ..etc?

I'm also curious.
As a brand new latex user this template is very helpful. But where does the \begin{proof} come from? What is the analogous expression to the exercise and question environment?
Thanks

I'm new to LaTeX and this got me started ... it is similar to learning HTML from a basic page with some level of detail. Very helpful :)
