# Write Maths in Forum: LaTeX Guide

• LaTeX
• Ibix
In summary, to write equations using LaTeX in a forum post, enclose the equation within two dollar signs (). You can include symbols and special characters using backslash (\) followed by the name of the symbol. To write fractions, use the \frac command and for exponents, use the carrot (^) symbol. Equations can be aligned using the align environment and ampersand (&). It is necessary to enclose LaTeX equations within two dollar signs () for them to be properly rendered in the forum post.

I suggest relabelling the "LaTeX guide" link, which is just below the reply box in threads. I think people who don't know LaTeX already don't necessarily recognise that this tells them how to write maths in the forum. Perhaps "How to write maths in the forum"?

Also, the guide isn't linked at all from the "Post thread" page.
