Hi Lars,

Because assumed multiplication is very difficult to interpret
correctly.
For example:
xy is that x*y or the variable xy?
23x
Is that 2*3*x or 23*x
f(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.

Today I will rely on the language of love and understanding.
If that doesn't work, I'll go back to intimidation and fear.
