ROMAN NUMERALS

Roman numerals are used chiefly on watch and clock faces, to number chapters, and to record dates on buildings and monuments. A knowledge of seven symbols and three rules will enable you to read and write Roman numerals.

[merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][ocr errors][merged small]

A horizontal line, or bar, placed over one of these symbols multiplies its value by 1,000. Thus, X = 10,000.

1. When a numeral is repeated, its value is repeated. 2. When a smaller numeral follows a larger, the two values are added together.

3. When a smaller numeral comes before a larger, the smaller value is subtracted from the larger value.
