WebModular arithmetic is basically doing addition (and other operations) not on a line, as you usually do, but on a circle -- the values "wrap around", always staying less than a fixed number called the modulus. To find, for example, 39 modulo 7, you simply calculate 39/7 (= 5 4/7) and take the remainder.
