\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. | |

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 :)
I'm also new to Latex and Ive been using this example for my homework. Thank you.
Huh, I missed the questions from 2013 and 2014. Sorry about that. Here are some responses 7 years late. The amsthm (short for AMS Theorem) package (loaded on line 9) provides the opportunity to use \begin{proof}...\end{proof}. Unfortunately, \begin{solution}...\end{solution} is not a thing that loads with any package (that I know of). However, you can "build" this environment as follows. Add the following line of code above \begin{document} but below \usepackage{amsthm,...}:
\newenvironment{solution}{\begin{proof}[Solution]}{\end{proof}}
This will allow you to use \begin{solution}...\end{solution} in your document. It will mimic the look of the output for the proof environment, but it will say "Solution." instead of "Proof."
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
