Man, I hate that so much. I swear this was half the reason I struggled with maths and physics, that these guys need to write this:
Rather than this:
At some point, they even collectively decided that not having to write a multiplication dot is more important than being able to use more than a single letter for your variables. Just what the fuck?
Thing is, you usually define all your variables. At least we do in engineering (of physical variety, rather than software).
Mostly because we can’t expect everyone reading the calculation to know, and that not everyone uses the same symbols.
Not explaining each variable is bad practice, other than for very simple things. (I do expect everyone and their dog reading a process eng calc to know PV=nRT, at a minimum).
Just like (in my opinion) not defining industry specific abbreviations is also bad practice.

Mathematicians don’t do this? Shame on them.
Try to write the above with pen and ink and then tell me if you can read it back yourself.
Single letters is not a good system but it was the less bad one.
