Hi Jay,
>* I seem to be having trouble using the <algebra> tag. For example, if
*>* use something like
*>*
*>* 1) <algebra>5*x = 10</algebra> the format looks exactly as expected.
*>*
*>* However, the following does _not_ come out looking right.
*>*
*>* 2) <algebra>5x = -10</algebra>
*>*
*>* Basically in case 2) above, the equals sign is missing. The formula I get on the screen looks like
*>* "5x-10".
*>*
*>* So, is this a problem with a setting on my computer or misuse of the <algebra> tag?
*
Looks like a bug in the <algebra> parser.
It apparently is treating = like - or plsue
so it's parsing
-10 = -10 -> -10 -10
Like it should
-10 + -10 -> -10-10
Trying to fix...
