# how to use this blog

You can type mathematical equations using LaTeX – just write “latex” after the first $sign. For example, to type $\Delta c = \sum c_{(1)} \otimes c_{(2)}$ you just need to write$latex \Delta c = \sum c_{(1)} \otimes c_{(2)}\$.

If you don’t know LaTeX, you should learn it. It is the one and only typesetting language that professional mathematicians use. You can see my favorite quick introduction to LaTeX by clicking here. You can see other useful tips on using LaTeX on wordpress blogs here.

I hope to be able to allow you to edit your comments after you’ve made them, particularly to check your LaTex. It seems that this is a tricky thing to arrange. If you know how to do this, please let me know.
