C.a.R.

C.a.R. uses HotEqn, a free, but not open sourced, software to display math. The syntax is a subset of LaTeX, a standard for mathematical texts.

To display LaTeX, use a text field, an alias for any object, or an expression description. In all these places, LaTeX is allowed. The code must be enclosed by $...$. E.g., you could name a point P subscript 1, setting its alias to $P_1$. Inside the LaTeX text %...% is allowed. The must be an expression, and will be replaced by the value of the expression.
