Base-N Arithmetic

The base both numbers are written in, from 2 to 36. The calculation and its result are shown in this base, with digits above 9 written as letters (a = 10).

The first operand, written in the chosen base. In base 2 for instance, only the digits 0 and 1 are allowed — 1011 is 11 in decimal.

The second operand, in the same base as the first. For division it must not be zero.
