Given
foot is m * s
v : foot
time : s
len : m
v = time * len
are len and time considered values because they are variables?
Yes, but the question is: what specific numeric values are they? I've changed
the assignment to make clear that variables initially contain an undefined,
non-numeric value, that, because it's non-numeric, can't be legally used in
computations.
I think of it as a syntax error, but I can see where you'd think of it as a
semantic error. Let's avoid the issue by just calling it "an error".
