Roman Numerals and Numbers
1. Numbers in Latin (Cardinals)
- 1:06 - #1-10
- 2:26 - #11-20
- 3:49 - #21, 30, 40...100, 101
- 4:13 - the 100s, 1000, thousands
- 4:59 - declining 1, 2 (6:01), and 3 (6:43)
- 7:00 - 100s are also declined
2. The Origin of Roman Numerals
More than you ever wanted to know about the development of the Roman Numerals. Nota Bene - he uses the additive way of counting (4 = IIII, 9 = VIIII), because it is the Classical Roman way. The subtractive method (4 = IV, 9 = IX) is the later way, and how Roman Numerals are used today.

- 2:58 - the unlikely explanation - though it is a good mnemonic for remembering the numerals
- 4:47 - the most likely explanation: A decimal system

Roman Numerals (again, he uses the additive method because it is Classical), and how the Romans did math. Addition is cool; multiplication is a nightmare - though people who like math will probably find it interesting.
