Hello,

Old, bad, habit die hard.

They was a requirement for ABC to be treated like A*B*C (because lots of math guys do that on paper).

It is astonishing for me to see how un-formal, and non rigorous most math teachers are. Whatever they do, a LOT of information is hidden in the, non written, context. This is one of them.
- Of course, when I write ABC I mean A*B*C!
- Of course, when I write ABC I mean the Angle formed by the AB and BC segment!
- Of course, when I write ABC I mean the Angle formed by the AB and AC segment (yes, verify these 2 are different, depending on your culture, you will use a different norm)!
- Of course, when I write ABC I mean the ABC variable!
- (silently in the programmer's head) Of course, let me just go ahead and implement a mind reading algorithm!

This feature is mostly useful for small, quick calculations, but as you so rightfully pointed out, it shoots you in the foot as soon as you try to do something more complex.

The main issue here is that the calculator needs to make everyone happy; and can't.

I am sorry that this is causing you issue.
