Learn Spanish Numbers 0-100: Count and Use Them with Ease

Cardinal numbers, or los números cardinales (e.g., uno - one, dos - two, tres - three), are a fundamental part of the Spanish language and a valuable resource for everything from counting and telling time to expressing age (e.g., Tengo catorce años- I am fourteen years old) and prices. Successful communication often relies on their correct use. While many numbers follow a discernible pattern, others follow a gender rule like: doscientos libros (two hundred books - masculine).

The Basics: Numbers 0-15

The foundation of Spanish numbers lies in memorizing the first sixteen, as these are unique and form the basis for many others.

Numbers 16-29: A Fused Formation

From sixteen to twenty-nine, the numbers are formed by combining diez (ten) or veinte (twenty) with the single-digit numbers. Notably, for the numbers 16 through 19 and the entire 20s series, this combination is written as a single word.

When to use Cardinal Numbers

Cardinal numbers sneak their way into almost every conversation without us even noticing! In Spanish (and in any language), they're used all the time for:

• Telling your age: Tengo veinticinco años (I’m 25 years old).
• Giving dates: Hoy es cinco de mayo (Today is May 5th).
• Talking about time or frequency: Comí tres veces hoy (I ate three times today).
• Counting objects: Hay cuatro sillas en la habitación (There are four chairs in the room).
• Giving addresses or phone numbers: Vivo en el número 122.
• Talking money: Eso cuesta cien córdobas (That costs one hundred córdobas).

And of course, they’re key in things like recipes, scores in sports, and even making plans

—Nos vemos a las seis (See you at six). 

The Hundreds: Gender Agreement and "Cien" vs. "Ciento"

When it comes to the hundreds, there are a few key rules to observe:
- 100: The number 100 is simply cien when it stands alone or precedes a noun (e.g., cien libros - 100 books). However, when it is part of a larger number, it changes to ciento (e.g., ciento uno - 101).
- 200-900: The hundreds are formed by combining the digit with -cientos. For example, 200 is doscientos, 300 is trescientos, and so on.

- Gender Agreement: The hundreds agree in gender with the noun they modify. For example:

- doscientos libros (two hundred books - masculine)
- doscientas plumas (two hundred pens - feminine)

Some of the hundreds have irregular forms:

- 500: quinientos (not cincocientos)
- 700: setecientos (not sietecientos)
- 900: novecientos (not nuevecientos)

Large Numbers: Thousands and Millions

- Thousands: The word for "thousand" is mil. It is invariable in the plural form when used as a number (e.g., dos mil - 2,000, not dos miles). "One thousand" is simply mil, not un mil.

- Millions: The word for "million" is millón. Unlike mil, millón is a noun and requires the use of "de" before another noun (e.g., un millón de personas - one million people). It also has a plural form, millones (e.g., dos millones de dólares - two million dollars).

Gender and "Uno"

The number uno and any number ending in -uno (like veintiuno, treinta y uno, etc.) changes to un before a masculine noun and una before a feminine noun.

- un libro (one book)
- una mesa (one table)
- veintiún años (twenty-one years)
- veintiuna chicas (twenty-one girls)

By understanding these rules and committing the basic numbers to memory, you will be well-equipped to use cardinal numbers effectively in Spanish.
