ROMAN NUMERALS (I – C)
1 = I
2 = II
3 = III
4 = 5 – 1 = V – I = IV,
Rule number 1,
- When a larger symbol comes after the smaller symbol, it is substation. That is, IV = V – I = 4
5 = V
6 = V + I = VI
Rule number 2,
- When a smaller symbol comes after the larger symbol, it is addition. That is, V + I = 6.
Rule number 3,
- Don’t use the same symbol more than three times in a row.
Read Roman numerals from 11 – 19.
