Numbers (los números)

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

2. 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.

3. 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 = dieciséis

   17 = diecisiete

   21 = veintiuno

   22 = veintidós

   23 = veintitrés

   26 = veintiséis

4. 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

5. 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”

Numbers 0 - 2.000.000

Ordinal Numbers

Ordinal numbers are adjectives that we use to rank things, name streets, etc. (i.e. 1^st, 2^nd, 3^rd, 4^th, 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 1^st and 3^rd (primer párrafo, tercer párrafo). Ordinal numbers are rarely used beyond 10 in Spanish.
