Hundreds and Number Composition

Number Agreement Rules

• Vingt (twenty) and cent (hundred) take an 's' in the plural when they are multiplied and not followed by another number:
  • quatre-vingts (eighty)
  • deux cents (two hundred)
• But we write:
  • quatre-vingt-un (eighty-one)
  • deux cent un (two hundred and one)
• Million and milliard are nouns and always take an 's' in the plural:
  • deux millions (two million)
  • trois milliards (three billion)

Invariable Numbers

In French, the only truly invariable number is:
thousand : It always remains singular, even when multiplied.

Examples:

• deux mille - two thousand
• trois mille - three thousand

Roman Numerals

Basic rules:

• Symbols are added from left to right
• A symbol placed to the left of a symbol of higher value is subtracted

Examples:

• II = 2
• IV = 4 (5 - 1)
• VI = 6 (5 + 1)
• IX = 9 (10 - 1)
• XXIII = 23 (10 + 10 + 3)
• XL = 40 (50 - 10)
• XCIX = 99 (100 - 10 + 10 - 1)
• MCMLIV = 1954 (1000 + (1000 - 100) + 50 + (5 - 1))
