Feb 23, 2025

Learning Objectives

By the end of this lesson, you will identify and understand the numbers from 0 to 100 in Spanish, practice forming numbers using the 'y' conjunction for numbers between 30 and 99, differentiate the terms 'cien' and 'ciento' when expressing numbers 100 and above, as well as apply the learned concepts to engage in everyday conversations involving age, prices, and other numerical discussions.

Introduction

Numbers are an essential part of any language, and Spanish is no exception. Mastering numbers from 0 to 100 will empower you to engage in everyday conversations, from sharing your age to discussing prices.

Basic Counting (0–15)

Here are the numbers you’ll frequently use in everyday conversation:

Number	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

Example Sentences
	Spanish	English	Information
	Tengo cinco libros.	I have five books.
	Hay doce estudiantes en la clase.	There are twelve students in the class.

Numbers 16–29

From 16 to 29, Spanish uses a “dieci-” or “veinti-” construction:

Number	Spanish	Construction
16	dieciséis	diez + y + seis → dieci + seis = dieciséis
17	diecisiete	diez + y + siete → dieci + siete = diecisiete
18	dieciocho	diez + y + ocho → dieci + ocho = dieciocho
19	diecinueve	diez + y + nueve → dieci + nueve = diecinueve
20	veinte	–
21	veintiuno	veinte + uno → veintiuno
22	veintidós	veinte + dos → veintidós
23	veintitrés	veinte + tres → veintitrés
24	venticuatro	veinte + cuatro → veinticuatro
25	veinticinco	veinte + cinco → veinticinco
26	veintiséis	veinte + seis → veintiséis
27	veintisiete	veinte + siete → veintisiete
28	veintiocho	veinte + ocho → veintiocho
29	veintinueve	veinte + nueve → veintinueve

Example Sentences
	Spanish	English	Information
	Mi hermano tiene diecinueve años.	My brother is nineteen years old.
	Necesito veintidós tomates.	I need twenty-two tomatoes.

The Tens:
30, 40, 50, 60, 70, 80, 90

Moving up in tens follows a consistent pattern:

Number	Spanish
30	treinta
40	cuarenta
50	cincuenta
60	sesenta
70	setenta
80	ochenta
90	noventa

To form numbers in between, add “y” and then the single digit. For example, 33 is treinta y tres, and 42 is cuarenta y dos.

Example Sentences
	Spanish	English	Information
	Treinta y cinco personas asisten a la fiesta.	Thirty-five people attend the party.
	El hotel tiene cuarenta y ocho habitaciones.	The hotel has forty-eight rooms.

Reaching 100

100 in Spanish is cien.

When describing numbers greater than 100, the word changes to ciento followed by the remaining digits (e.g., 101 = ciento uno), but for this lesson, we’ll focus on 0–100.

Example Sentences
	Spanish	English	Information
	Hay cien páginas en este libro.	There are one hundred pages in this book.

Conclusion

Congratulations! You now have a solid understanding of Spanish numbers from 0 to 100. Keep practicing them in real-life settings to gain confidence and fluency.
