You don't.

The Greeks and Romans had no concept of 0 as a number, which is interesting since it appears the Babylonians did.

It's really in the Hindu-Arabic system with place value that 0 becomes a number.

Answer: You CAN have 4. You just can't have 5. Also, only one of V, L and D.

And any number greater than MMMMDCCCCLXXXXVIIII isn't really expressible (although there have been some conventions made. M is supposed to denote a million, for example.)

MMCMXCIX

(I almost wrote MMCMXCLXXXIV, but that's not a valid roman numeral.)

When I was young I thought they were "Roman Numberals" which was just a fancy way of saying "Roman Numbers."
