It is important that we know how to count in Spanish. So, let us look at the way we write out the numbers as words in Spanish.
0 = cero
1 = uno
2 = dos
3 = tres
4 = cuatro
5 = cinco
6 = seis
7 = siete
8 = ocho
9 = nueve
10 = diez
11 = once
12 = doce
13 = trece
14 = catorce
15 = quince
16 = diéciseis
17 = diecisiete
18 = dieciocho
19 = diecinueve
20 = veinte
21 = veintiuno
22 = veintidós
23 = veintitrés
24 = veinticuatro
25 = veinticinco
26 = veintiséis
27 = veintisiete
28 = veintiocho
29 = veintinueve
30 = treinta
31 = treinta y uno
32 = treinta y dos
Now we will only have to learn a new number for the tens digit because we add y and the ones digit.
33 = treinta y tres
34 = treinta y cuatro
40 = cuarenta
41 = cuarenta y uno
42 = cuarenta y dos
50 = cincuenta
51 = cincuenta y uno
52 = cincuenta y dos
60 = sesenta
61 = sesenta y uno
62 = sesenta y dos
70 = setenta
71 = setenta y uno
72 = setenta y dos
80 = ochenta
81 = ochenta y uno
82 = ochenta y dos
90 = noventa
91 = noventa y uno
92 = noventa y dos
100 = cien/ciento
When saying the number 100 alone, we use the word cien. When it is used before another number it becomes ciento. For example
140 = ciento cuarenta
185 = ciento ochenta y cinco.
Note how we only use the word y, or and, for the numbers between sixteen and ninety-nine.
veinte y tres
cincuenta y cuatro
sesenta y siete
We do not use it in larger numbers.
ciento veinte y tres
ciento cincuenta y cuatro
ciento sesenta y siete
Some important terms to know with numbers are
dividir to divide
multiplicar to multiply
restar to subtract
sumar to add
+ más
- menos
x por
/ dividido por
= es/son/es igual a
Numbers are useful and fun to use. So, now let’s practice.
Prácticas.
A. With a partner, practice counting to one hundred.
B. Write out the numbers in the word form in Spanish.
1. 10
2. 13
3. 15
4. 20
5. 25
6. 37
7. 49
8. 56
9. 52
10. 63
11. 74
12. 79
13. 88
14. 91
15. 100
B. Complete each number series.
1. dos, cuatro, seis, __________________, __________________, ____________________
2. diez, veinte, ___________________, ____________________, ____________________
3. sesenta, setenta, __________________, ____________________, ___________________
4. cinco, diez, ____________________, __________________, ____________________
5. cincuenta y tres, cincuenta y seis, ____________________, ____________________, ____________________
C. Complete the following math problems in Spanish.
1. 22 + 12 =
2. 5 + 32 =
3. 50 + 16 =
4. 31 + 14 =
5. 90 + 9 =
6. 70 – 32 =
7. 84 – 15 =
8. 100 – 49 =
9. 35 – 20 =
10. 60 – 19 =
11. 2 x 30 =
12. 10 x 5 =
13. 22 x 4 =
14. 50 x 2 =
15. 15 x 3 =
16. 90 / 3 =
17. 100 / 25 =
18. 99 / 3 =
19. 50 / 25 =
20. 80 / 2 =
