What are all the Roman numerals and what do they mean?

Answer 1

The Roman numeral system works by having separate symbols to represent different numbers but unlike our system there was no symbol for zero. Essentially we have 9 numbers and then add a zero on the end to denote 10s, two zeros to denote 100s and so on. the Romans simply had additional symbols to denotes 10s, 100s etc. Examples of Roman numerals and how they are worked out follows...

1 = I

2 = II (1 + 1)

3 = III (1+ 1 + 1)

4 = IV (1 before 5)

5 = V

then the system repeats...

6 = VI (5 + 1)

7 = VII (5 + 1 + 1)

8 = VIII (5 + 1 + 1 + 1)

9 = IX (1 before 10)

10 = X

Additional numerals exist for 50 (L), 100 (C), 500 (D) and 1000 (M) and they work on the same system so, for example...

XX = 20

XXX = 30

XL = 40

CCC = 300

CD = 400

CM = 900

Answer 2

The Roman numerals are: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). These numerals represent a numerical system that was widely used in ancient Rome. They are based on specific combinations and arrangements of these symbols to represent different numbers. For example, the numeral II represents 2, while XIII represents 13.
