The French cardinal numbers, those used for counting, require you to use math skills once you get past 69. The number 70 is formed by adding 60 + 10, 71 is 60 + 11, and so on until 80 is reached. The number 80 is 4 × 20, while 81 is 4 × 20 + 1, and so on through the number 99.
Consult Table 1 for a list of French cardinal numbers that you should know.
| Number | French | | 0 | zéro | | 1 | un | | 2 | deux | | 3 | trois | | 4 | quatre | | 5 | cinq | | 6 | six | | 7 | sept | | 8 | huit | | 9 | neuf | | 10 | dix | | 11 | onze | | 12 | douze | | 13 | treize | | 14 | quatorze | | 15 | quinze | | 16 | seize | | 17 | dix-sept | | 18 | dix-huit | | 19 | dix-neuf | | 20 | vingt | | 21 | vingt et un | | 22 | vingt-deux | | 30 | trente | | 40 | quarante | | 50 | cinquante | | 60 | soixante | | 70 | soixante-dix | | 71 | soixante et onze | | 72 | soixante-douze | | 80 | quatre-vingts | | 81 | quatre-vingt-un | | 90 | quatre-vingt-dix | | 91 | quatre-vingt-onze | | 100 | cent | | 101 | cent un | | 200 | deux cents | | 201 | deux cent un | | 1,000 | mille | | 2,000 | deux mille | | 1,000,000 | un million | | 2,000,000 | deux millions | | 1,000,000,000 | un milliard | | 2,000,000,000 | deux milliards | |
Note the following about cardinal numbers:
-
The conjunction et (and) is used only for the numbers 21, 31, 41, 51, 61, and 71. In all other compound numbers through 99, et is dropped and a hyphen is used.
-
Before a feminine noun, un becomes une.
-
For quatre-vingts (80) and the plural of cent (100) for any number above 199, drop the -s before another number, but not before a noun. The -s is also dropped when these numbers are used in an ordinal sense (for example, to express page or address numbers and dates).
-
quatre cent vingt dollars (420 dollars)
-
quatre cents dollars (400 dollars)
-
quatre-vingt-dix-neuf euros (99 euros)
-
quatre-vingts euros(80 euros)
-
à la page deux cent (on page 200)
-
dans la rue quatre-vingt (on 80th Street)
-
pendant l'année neuf cent (during the year 900)
-
Un is not used before cent (100) and mille (1,000).
-
Mille doesn't take -s in the plural.
-
Mille is generally written mil in dates until 1999:
-
Je suis né en mil neuf cent quarante-sept. (I was born in 1947.)
-
Starting with the year 2000, the date is written as follows:
-
Ma fille est née en (l'an) deux mille. (My daughter was born in 2000.) When another number is added after 2000, mil is generally preferred to mille.
-
Mon fils est né en (l'an) deux mil( le) deux. (My son was born in 2002.)
-
To express numbers between 1,000 and 9,999, you can avoid using mille and simply use cent where it is more convenient.
-
In numerals and decimals, the French use commas where Americans use periods, and vice versa:
| English | French | | 50,000 | 50.000 | | 025 | ,25 | | $25.99 | $25,99 | |
Numbers and Nouns of Quantity
Nouns that are used to express a quantity or a measure are followed by de + noun. The cardinal numbers million and milliard, as well as other nouns of number, follow this rule.
-
un million de touristes (a million tourists)
-
onze milliards de gens (11 billion people)
-
deux boîtes de céréales (2 boxes of cereal)
-
un tas de papiers (a pile of papers)
Refer to Table 2 for common nouns of number and quantity.
| TABLE 2 | Numbers and Nouns of Quantity | | Noun of Quantity | English | | une boîte de | a box of, a can of | | une bouteille de | a bottle of | | une centaine de | about 100 | | une dizaine de | about 10 | | une douzaine de | a dozen | | un kilo de | a kilogram of | | un litre de | a liter of | | une livre de | a pound of | | un milliard de | a billion | | un millier de | about a thousand | | un million de | a million | | un morceau de | a piece of | | une paire de | a pair of | | un paquet de | a package of | | une quinzaine de | about 15 | | un sac de | a bag of | | un tas de | a pile of | | une tasse de | a cup of | | une tranche de | a slice of | | un verre de | a glass of | | une vingtaine de | about 20 | |
Arithmetic
To calculate simple arithmetic problems in French, use the following:
| To add: | Dix et (plus) cinq font (égale) quinze. | 10 + 5 = 15 | | To subtract: | Quinze moins cinq font (égale) dix. | 15 − 5 = 10 | | To multiply: | Cinq fois cinq font (égale) vingt-cinq. | 5 × 5 = 25 | | To divide: | Vingt-cinq divisé par cinq font (égale) cinq. | 25 ÷ 5 = 5 | |
Ordinal Numbers
In French, most ordinal numbers (those used to show rank or placement) are formed by adding -i`me to the cardinal number. When the cardinal number ends in a silent e, that vowel is dropped before adding the ordinal ending ( quatri`me is “fourth,” onzi`me is “eleventh,” and so on). Consult Table 3 for exceptions to the rule.
| TABLE 3 | Exception Ordinal Numbers | | Ordinal | French | | 1st | premier or premi`re | | 2nd | deuxi`me or second( e) | | 5th | cinqui`me | | 9th | neuvi`me | | 21st | vingt et uni`me | |
Note the following about ordinal numbers:
-
Premier and premi`re are abbreviated as follows:
-
premier: 1er
-
premi`re: 1re
-
All others ordinals get a superscript e.
-
Ordinal numbers agree in number and gender with the nouns they describe. Premier (premi`re)and second (seconde) are the only ordinal numbers that have a feminine form.
-
le premier acte (the first act)
-
la premi`re pi`ce (the first play)
-
les premi`res années (the first years)
-
la Seconde Guerre mondiale (the second World War)
-
les vingt et uni`mes anniversaires (21st birthdays)
-
Premier is used only for the first in a series. For 21 to 71, uni`me is added after the conjunction et to express first, and it must agree in number with the noun it modifies.
-
Second(e) is generally used in a series that goes no higher than two.
-
Use le or la before huit/huiti`me and onze/onzi`me. There is no elision.
-
In French, cardinal numbers precede ordinal numbers.
Fractions
Just as in English, French fractions are formed by combining a cardinal and an ordinal number:
| un cinqui`me | 1/5 | | deux septi`mes | 2/7 | | trois huiti`mes | 3/8 | | quatre centi`mes | 4/100 | |
The most common fractions are irregular:
| un demi (une moitié) | ½ | | un tiers | 1/3 | | trois quarts | 3/4 | |
Note the following:
-
Demi is generally used as an adjective. When it is used before the noun with a hyphen, it does not agree with the noun it describes. When used after the noun, however, it must agree with the noun it modifies.
-
Moitié is a feminine noun and must be used with the article la.
Multiples
Multiple numbers are used in French in the same way they are used in English:
| une fois | one time | | vingt fois | 20 times | | mille fois | 1,000 times | | simple | a single, simple | | double | a double | | triple | a triple | |
Here are some examples of multiples used in a sentence:
Titles of Rulers
In numerical titles of rulers, cardinal numbers are used (except for premier).
| François premier (François Ier) | François the First | | Henri Huit (Henri VIII) | Henry the Eighth | | Louis Quinze (Louis XV) | Louis the Fifteenth | |
