Harshad Number

Two New Fiat 500, LivornoA Harshad number, or Niven number in a given number base, is an integer that is divisible by the sum of its digits when written in that base. Harshad numbers were defined by D. R. Kaprekar, a mathematician from India. The word “Harshad” comes from the Sanskrit harṣa (joy) + da (give), meaning joy-giver. (Wikipedia)

1000 is a typical Harshad number and it really gives us joy, but for an almost unmathematical reason: this is our thousandth post! Considered that the only thing around containing this number was an unexploded 1000-pound bomb, we settled for two Fiat 500.
