The Numbers in Spanish

From 0 to 10:

Every number is different and we need to learn each one individually:

0cero
1uno
2dos
3tres
4cuatro
5cinco
6seis
7siete
8ocho
9nueve
10diez

 

From 11 to 15:

Every number is still different, but at least there is a trick: all off them end in “ce”.

11once
12doce
13trece
14catorce
15quince

 

From 16 to 19:

They are still written in one word, and it’s always “dieci_____”:

16dieciséis
17diecisiete
18dieciocho
19diecinueve

 

From 20 to 29:

20 is written “veinte”, and the rest are still written in one word, and it’s always “veinti____

20veinte
21veintiuno
22veintidós
23veintitrés
24veinticuatro
25veinticinco
26veintiséis
27veintisiete
28veintiocho
29veintinueve

 

From 30 to 99:

When there are ones in the number, it’s written in 3 words. For example 35 = “thirty and five” = treinta y cinco.

30treinta
31treinta y uno
32treinta y dos
40cuarenta
43cuarenta y tres
50cincuenta
60sesenta
70setenta
80ochenta
90noventa
99noventa y nueve

 

Exactly 100:

We use the word “cien” only when it’s exactly one hundred, without tens or units.

100cien

 

From 101 to 999:

We need to learn the word for every hundred. If there are tens and ones, there is no word “y” after the hundreds.

101ciento uno
110ciento diez
146ciento cuarenta y seis
200doscientos
280doscientos ochenta
300trescientos
388trescientos ochenta y ocho
400cuatrocientos
500quinientos
600seiscientos
700setecientos
800ochocientos
900novecientos
999novecientos noventa y nueve

 

From 1.000 to 1.999:

It’s always “mil” plus the rest of the number. No word “y” after the thousands either:

1.000mil
1.003mil tres
1.040mil cuarenta
1.872mil ochocientos setenta y dos

 

From 2.000 to 999.999:

The trick is to divide it mentally in two numbers: the number before the point, and the number after the point.

Then, say each one of those 2 numbers using the system we have learn until this point.

Just add the word “mil” between the two numbers:

2.000dos mil
2.001dos mil uno
2.480dos mil cuatrocientos ochenta
4.300cuatro mil trescientos
37.000treinta y siete mil
37.600treinta y siete mil seiscientos
125.125ciento veinticinco mil ciento veinticinco
472.346cuatrocientos setenta y dos mil trescientos cuarenta y seis
999.999novecientos noventa y nueve mil novecientos noventa y nueve

 

From one million on:

We say how many millions there are, plus whatever comes next. No “y” after the millions either:

1.000.000un millón
2.000.000dos millones
3.500.000tres millones quinientos mil
55.248.248cincuenta y cinco millones doscientos cuarenta y ocho mil doscientos cuarenta y ocho
