|The ancient Romans counted their numbers using letters! The numbers that we use are called Arabic numbers, as the Europeans learnt them from the Arabs, although they were invented in India. The Romans had a very different system of numbering. They didn't have the number 0 (zero), or negative numbers, or fractions. In fact, in their first numbering system they only had integer numbers between 1 and 3999 inclusive. No other numbers were ever needed.
