n (mathematics) The amount left over after subtracting the
divisor as many times as possible from the
dividend without producing a
negative result. If
(n) (dividend) and
d (divisor) are integers, then
(n) can always be expressed in the form
n = dq + r, where
q (
quotient) and
r (
'remainder') are also integers and 0 ≤
r <
d.
