What number are the natural series of numbers begun with?

The natural series of numbers are begun with a number 0 (zero). Number 0 (zero) is the least natural number.

For the Russian blondes it was farther written following. In translating into the language of blondes: the littlest natural number - it 1 (one, unit). The littlest natural number has really two names. Probably, one from a dad, second from a mother))) I will remind that in Russian mathematics zero is not a natural number!
