\mathbb{stuff} isn't working

[flyingpig]

Homework Statement

On MikTeX, can't enter $\mathbb{R}$

Gives me a statement that says

! Undefined control sequence.
<recently read> \mathbb 
                        
l.14 $\mathbb
             {F}$
?

No idea what that means?

\mathbb is defined in one of the AMS packages, so you probably have to include amssymb or amsfonts or something like that.

I am a novice in this, how do I introduce that package?

Following should work:

\documentclass{article}
\usepackage{amsfonts}
\begin{document}
$\mathbb{R}$
\end{document}

 

[flyingpig]

Following should work:

\documentclass{article}
\usepackage{amsfonts}
\begin{document}
$\mathbb{R}$
\end{document}

That worked, but am I restricted to only one package? Again novice here.

I tried adding \userpackage{amsmath}, but amsmath doesn't exist. I am trying to add an array here.

thanks

I'm not aware of any limitation on how many packages can be used. Whenever I include a reference to a new package MiTek automatically finds and installs it. Btw, I noticed a typo in your last post. It should be \usepackage not \userpackage.

Suggestion: the userguides you can find on the web are quite helpful. Just do a Google search and you'll find a number of them.

There is also a Google Latex user group that can be quite helpful:

Yes you are right, I added an "r". I also have looked online, but I thought there was something wrong with it because it didn't work initially and it was the "r" and I thought the package doesn't even exist.

Thanks
