Downloaded TeXworks a couple weeks ago and have been using it to type my mathematics homework in LaTeX. I keep having to write sentences such as: Let $n$ be an integer. There are times when I would much prefer to write similar statements in symbols. For example: Let $n \in \mathbb{Z}$. But every time I click to compile I get a message saying \mathbb{Z} is not recognized. I am assuming this is because I am not loading the proper package.
I am writing \usepackage{amsmath} before I begin the document. Should I be loading a different or additional package to be able to use these additional symbols, such as the symbol for the integers? If so, what package?
\usepackage{amssymb}to your preamble. This is also covered in the Comprehensive LaTeX Symbol List (Table 213, p 68). – Werner Mar 12 '14 at 05:15
