Why learn number patterns, not just memorization
Memorizing individual words helps, but Portuguese numbers follow consistent patterns that let you build new numbers from known pieces. Once you know the building blocks for 0–20, tens (30, 40, 50…), and 100, you can construct most numbers you will encounter. This approach saves time and reduces errors in real conversations.
Core number vocabulary (0–20)
Learn these first because they are the foundation for larger numbers and daily phrases.
zero — zero
um — one (used for masculine nouns)
uma — one (used for feminine nouns)
dois — two (masculine)
duas — two (feminine)
três — three
quatro — four
cinco — five
seis — six
sete — seven
oito — eight
nove — nine
dez — ten
onze — eleven
doze — twelve
treze — thirteen
quatorze — fourteen
quinze — fifteen
dezesseis — sixteen
dezessete — seventeen
dezoito — eighteen
dezenove — nineteen
vinte — twenty
Build tens and compound numbers
After 20, Portuguese forms tens differently. The tens themselves are unique words, and compound numbers are usually tens plus units joined by a hyphen or a space in writing, but spoken without an extra connector like and.
Key tens
vinte — 20
trinta — 30
quarenta — 40
cinquenta — 50
sessenta — 60
setenta — 70
oitenta — 80
noventa — 90
cem — 100 (used exactly for 100)
cento — 100 (used as a prefix for 101–199)
How to combine tens and units
Pattern: tens + e + unit is common in formal speech for some contexts, but many Brazilians simply say tens + unit when fast speaking. Beginners should learn both. Example: 21 = vinte e um, 34 = trinta e quatro, 58 = cinquenta e oito.
Examples:
vinte e um — twenty-one
Exemplo: Tenho vinte e um anos.
trinta e quatro — thirty-four
Exemplo: O ônibus sai às trinta e quatro minutos? (More natural: O ônibus sai às três e trinta e quatro is uncommon; see time section.)
cinquenta e oito — fifty-eight
Exemplo: O preço é R$ cinquenta e oito, por favor.
Hundreds, thousands, and big numbers
Portuguese groups numbers similarly to English but uses different words. Notice gender agreement for one and two when used with nouns.
Hundreds
cem — 100 (standalone)
cento — used with other numbers from 101 to 199, for example cento e cinco — 105.
duzentos — 200 (masculine)
duzentas — 200 (feminine)
trezentos — 300
quatrocentos — 400
quinhentos — 500
seiscentos — 600
setecentos — 700
oitocentos — 800
novecentos — 900
Examples:
duzentos e vinte — 220
Exemplo: A passagem custa R$ duzentos e vinte.
cento e cinco — 105
Exemplo: Número da sala: cento e cinco.
Thousands and beyond
mil — thousand (no plural marker for numbers: dois mil = 2000)
milhão — million; plural milhões
Examples:
dois mil — 2000
Exemplo: O hotel fica a dois mil metros daqui.
um milhão — 1,000,000
Exemplo: A loteria tem um prêmio de um milhão.
Practical uses: time, prices, phone numbers, dates
Beginner-friendly phrases for everyday contexts help you use numbers immediately.
Time
Portuguese expresses time with hours and minutes similar to English. Use horas for hours and minutos for minutes. For 1 o’clock use uma hora.
São + hour(s) + e + minutes is common. For half past, use meia.
Examples:
São duas horas — It is two o’clock
Exemplo: São duas horas, vamos sair?
São três e quinze — 3:15 (or três quinze in informal contexts)
Exemplo: O filme começa às três e quinze.
São oito e meia — 8:30 (use meia for half past)
Exemplo: A reunião é às oito e meia.
Prices and money
Brazil uses the real, abbreviated R$. Say the amount and then reais, cents are centavos. Use e to join reais and centavos.
Examples:
R$ vinte — R$20.00
Exemplo: Quanto custa? — R$ vinte.
R$ trinta e cinco, cinquenta — R$35.50
Exemplo: O suco custa R$ trinta e cinco, cinquenta.
Phone numbers and digits
When giving digits, say each number separately. Use zero, one, two… but say um/uma for single 1 is common in some contexts; say dígitos for digits.
Example: For 21987654321 (typical cellphone), you might say:
dois um nove oito sete seis cinco quatro três dois um
Exemplo: Meu número é dois um nove oito sete seis cinco quatro três dois um.
Dates
Dates often use day de month de year. Months are nouns and not capitalized in Portuguese.
Example:
vinte e cinco de dezembro de dois mil e vinte e três
Exemplo: Meu aniversário é vinte e cinco de dezembro de dois mil e vinte e três.
Common beginner phrases using numbers
Short practical sentences you can use right away.
Quantos anos você tem? — How old are you?
Resposta: Eu tenho vinte e oito anos.
Quanto custa? — How much is it?
Resposta: Custa trinta e nove reais.
Que horas são? — What time is it?
Resposta: São quatro e quinze.
Qual é o seu número? — What is your number?
Resposta: Meu número é nove oito sete seis cinco quatro três dois.
Pronunciation tips and common mistakes
Focus on rhythm and linking. Portuguese often blends words so numbers can sound faster than English. Here are precise tips to avoid common errors.
Stress and vowel reduction
Many unstressed vowels are reduced; listen and imitate native audio. For example vinte sounds like VIN-ti, not VIN-tee.
Using um vs uma, dois vs duas
Remember gender agreement when numbers modify nouns. Use uma with feminine nouns and um with masculine nouns. Examples: uma casa, um carro; duas maçãs, dois livros.
cem vs cento
Use cem only for exactly 100. Use cento when adding units: cento e um is 101. This is a frequent beginner mistake.
O and H sound in hora vs hora expressions
Portuguese h is silent, so hora is pronounced ORA. Use duas horas for two hours; do not add extra sounds.
Practice drills and realistic mini-dialogues
Short drills you can repeat aloud or use with a partner. Replace numbers to make more examples.
Drill 1: Say price and count change.
Cliente: Quanto custa?
Vendedor: Custa R$ trinta e cinco.
Cliente: Aqui está R$ cinquenta. Quanto é o troco? — O troco é R$ quinze.
Drill 2: Appointment scheduling.
Pessoa A: Você pode às nove?
Pessoa B: Não, às nove e meia eu tenho outra reunião. Pode às dez?
Pessoa A: Perfeito, às dez então.
Drill 3: Phone number exchange.
Pessoa A: Qual é seu número?
Pessoa B: É nove três dois quatro cinco seis sete oito. Repete?
Pessoa A: Nove três dois quatro cinco seis sete oito. Obrigado.

Common mistakes and how to fix them
Be aware of repeated errors and quick corrections.
Mistake: Saying cento instead of cem for exactly 100. Fix: memorize the special case cem.
Mistake: Forgetting gender with one and two. Fix: practice with common nouns: uma cadeira, um copo, duas garrafas, dois bancos.
Mistake: Dropping e in formal situations. Fix: use e between tens and units until you feel comfortable with natural speech.
Resources and next steps
Use audio resources to hear natural rhythm. Practice with simple tasks: read prices on a menu, say bus times, and repeat phone numbers. Pair numeric drills with nouns you encounter daily so you link numbers to real contexts.
Conclusion
Learning Portuguese numbers through patterns makes them practical fast. Focus on the 0–20 base, tens, hundreds, and the key rules for gender and cento/cem. Practice with real-life examples like times, prices, and phone numbers to build confidence and fluency in everyday Brazilian Portuguese.
