Question

Example 12: A box contains 3 red, 3 blue and 4 white socks. In how many ways can socks be pulled out of the box, one at a time, if order is important?​

Answer 1

Answer:

Roman number system does not contain the number zero. The roman number system was basically designed to estimate the prices of goods and trading business. So the roman system did not need any value to represent zero. But instead of zero, the word nulla was used by the Romans to specify zero.
