Because assumed multiplication is very difficult to interpret

For example:

xy is that x*y or the variable xy?


Is that 2*3*x or 23*x


is that f*(x) or the function f with an argument of x

For most of these cases I can try to heuristically guess what one
meant but it can become quite troublesome.

Future Plans:

We will be moving away for the simple formula interpreter that we
inherit from CAPA and will be adding in a full Mathematics Kernal
called MuPad.
