## 0-10

0…………………………………………………………………………………..…………...cero

1……………………………………………………………………………………...………...uno

2………………………………………………………………………………………………...dos

3………………………………………………………………………………………………...tres

4…………………………………………………………………………………………......cuatro

5……………………………………………………………………………………………...cinco

6……………………………………………………………………………………………......seis

7……………………………………………………………………………………………….siete

8…………………………………………………………………………………………….....ocho

9……………………………………………………………………………………………...nueve

10……………………………………………………………………………………………....diez

One through Nine are absolutely critical—master them!

## 11-15

11…………………………………………………………………………………..…………..once

12……………………………………………………………………………………..………..doce

13………………………………………………………………………………………..……..trece

14……………………………………………………………………………………….……catorce

15………………………………………………………………………………………….....quince

Eleven through Fifteen are tricky—spend extra time on them.

## 16-19

16…………………………………………………………………………………..…….....dieciséis*

17…………………………………………………………………………………………..diecisiete

18…………………………………………………………………………………………..dieciocho

19……………………………………………………………………………………….…diecinueve

*When a single-digit one-through-nine number (2, 3, 6) is attached to another, it takes an accent.

## 20-29

20…………………………………….…veinte 25………………………………...…veinticinco

21……………………………..……veintiuno** 26………………………………….…veintiséis

22…………………………………….veintidós 27………………………….……...…veintisiete

23…………………………………….veintitrés 28…………………….………......…veintiocho

24………………………………….veinticuatro 29……………………………......…veintinueve

**When a masculine noun immediate follows “uno,” the –o drops and the u take an accent.

- Tengo veintiún años.

The –e in veinte changes to an “i” when connecting a 1-9 number. This mimics the “and” sound: “y.”

## 30-39

30…………………………………….…treinta 35………………………………...treinta y cinco

31……………………………...treinta y uno** 36………………………………….treinta y seis

32………………………………...treinta y dos 37………………………………….treinta y siete

33………………………………...treinta y tres 38………………………………...treinta y ocho

34………………………………treinta y cuatro 39……………………………….treinta y nueve

Once we get to “treinta,” things get much easier: Thirty and one, thirty and two…. Thirty and six... etc.

## 40-100

40…………………….……………….cuarenta 70…………………….…………....……setenta

50…………………….………………cincuenta 80…………………….………..………ochenta

60…………………….……………...…sesenta 90…………………….…………..……noventa

100………………………………………………………………………………………..………cien

That pattern continues for the rest of the “tens”

##### Note

“Cien” works for 100 “on the dot” only. We will see larger numbers later, but it is worth noting that after 100 (101, etc), “hundred” is “ciento.”
