Hi Hon-Kie,

I expect so.

BTW it handles

<algebra>a--b+-c-+d</algebra> converting it to a+b-c-d

<algebra>(x^2+x)/(y^2+2y)</algebra> -> \frac{x^{2}+x}{y^{2}+2 y}

the idea behind algebra is to make things easy to input, if you want
complete control over what it looks like, <m> is for that.

Nope.

<m> needs it because $ means someting in LaTeX, but $ doesn;t mean
anything in algebra so I can handle

<algebra>x^$pow+$constant</algebra>

just fine.

BTW almost all of the code doing this was grab from Moodle who got it
from WebWork.
