Why Isn't \mathbb Working in My Latex Document?

[Zurtex]

Hey

I'm wanting to write up a small paper so I've installed various Latex things on my computer, I have the full Miktex package and I have TexnicCenter, I want to write something like:

\text{For all x, y} \, \in \mathbb{N}

But the mathbb bit doesn't seem to be working, I can get mathrm and mathbf, but these aren't the fonts I want, can anyone help me please.

 

[matt grime]

make sure you've got

\usepackage{amssymb}

in the preamble, and plenty of other pckages.

google to find out which package provides mathbb ot make sure I've got it right.

You could use Open Office Maths. Its quick, easy and free. http://www.openoffice.org/"

But quite painful to do full maths papers, I've found it useful to do maths homework but anything like papers or coursework it just doesn't have the functionality for.

Plus it doesn't actually have all the symbols I require most the time and I end up depending on Mathematica fonts.

Anyway thanks matt, I think I've about worked it out but I spotted a mistake in my proof so I've been trying quite desperately to patch it up.

Hey Zurtex, you can try http://www.dessci.com/en/products/mathtype/
MathType is quiet easy to learn and
has several advanced functions.

Mathtype can convert to \LaTeX, MathML,...or you can just inline your equations as simple images. It is compatible with Microsoft Word, and you can later distill your documents into PDF files.

As a bit of inspiration, here are an old .sty file and a template i used some time ago. place both files quoted below in the same directory and compile. works fine with my MikTeX (do note that not all enviroments in the style file work!, but the template compiles fine).


First here is "projects.sty":

Hey Zurtex, you can try http://www.dessci.com/en/products/mathtype/

has several advanced functions.

Mathtype can convert to \LaTeX, MathML,...or you can just inline your equations as simple images. It is compatible with Microsoft Word, and you can later distill your documents into PDF files.

Same problem with Mathtype as I have with open office, just doesn't work for writting lots of stuff. Mathtype is even worse really because of its wysiwyg interface.

Thanks Triss, I'll try it out
