## Cardinal Numbers

Cardinal numbers are the numbers we use to count (i.e., 1, 2, 3, 4, 5, etc.).

1. The spelling of uno changes depending on the gender of the noun it modifies. Uno is spelled un before a masculine noun and una before a feminine noun.
Ejemplo(s):
--un ejemplo (m.)
an example

--
una pregunta (f.)
a question
1. Mil (1,000) is not pluralized when it is part of a specific number. Millón is pluralized.
Ejemplo(s):
--veinte mil, cien mil
twenty thousand, one hundred thousand

--
dos mil dólares ($2,000) two thousand dollars -- --dos millones de dólares ($2,000,000)
two million dollars
2. Mil may be used in the plural in more general statements.
Ejemplo(s):
--Miles de personas visitan 'El Parque de la Amistad' en Tijuana.
Thousands of people visit 'El Parque de la Amistad' in Tijuana.
2. Numbers 16 to 29 are commonly written as one word or as two words connected by "y" (and). An accent is added to the one-word spelling of 16, 22, 23 and 26.
Ejemplo(s):
16 = dieciséisé
17 = diecisiete
21 = veintiuno
22 = veintidós
23 = vientitrés
26 = veiniséis
1. Cien is used for the number 100 and before all nouns.
2. To say 101, 102-199, the form ciento is used.
Ejemplo(s):
--ciento uno, ciento dos, ciento noventa y nueve.
3. When plural (200-999) an -os or -as is added depending on the gender of the noun.
Spanish English
Cien 100 or one hundred
Cien dólares 100 dollars
Cien páginas 100 pages
Ciento un dólares 101 dollars
Doscientos dólares 200 dollars
Doscientas páginas 200 pages
3. Spanish uses “.” (points) and “,” (commas) differently than English does. Points are used where one would expect a comma in English and vice versa.
 Spanish English 1.000 (mil) 1,000 (one thousand) 1.000.000 (un millón) 1,000,000 (one million) 86,5% 86.5% “ochenta y seis con 5 por ciento” “eighty six point five percent”

 1.000.000 un millón 2.000.000 dos millones

## Ordinal Numbers

Ordinal numbers are adjectives that we use to rank things, name streets, etc. (i.e. 1st, 2nd, 3rd, 4th, etc.). The last letter of ordinal numbers is variable so that it agrees in gender and number with the noun it modifies (like all adjectives). However, the "o" is dropped before masculine nouns for 1st and 3rd (primer párrafo, tercer párrafo). Ordinal numbers are rarely used beyond 10 in Spanish.
