There are a couple of borderline cases: if we are looking only at the
final digit (or the digital
root), is that base, or just modulus?
Me: that is base-dependent, so it would
get the keyword base
Likewise, should "the number of
X between 10^n and
10^{n+1}" be considered base?
Me: no, because that is not base-dependent
