Only if they are well-known in the language you’re using or domain you’re writing for. x and y are fine for coordinates. i and j are fine for loop indices. But abbreviating things unnecessarily is bad IMO. s = GetSession() is too terse, for example.
No, I mean single-letter vars are standard in physics and math, but reusing vars is not acceptable. Obviously they’re not good practice except in the scenarios you describe, but mathies gonna math.
When you are used to math equations, it’s easy to slip into that habit.
Single letter variables, yes. Reusing them? No.
