Why numbers matter for beginners
Numbers appear in nearly every basic interaction: telling time, paying, giving your phone number, reading addresses, or ordering food. Mastering numbers gives immediate communicative power and helps you navigate Brazil with more confidence. Many beginner errors come from pronunciation, gender agreement, and false friends, so focusing on numbers early saves time and embarrassment.
Core number vocabulary: 0–20
Start with the first 21 numbers: they form the foundation for larger numbers.
0 zero
1 um / uma
2 dois / duas
3 três
4 quatro
5 cinco
6 seis
7 sete
8 oito
9 nove
10 dez
11 onze
12 doze
13 treze
14 quatorze
15 quinze
16 dezesseis
17 dezessete
18 dezoito
19 dezenove
20 vinte
Tip
Pay attention to gender with 1 and 2: um/uma and dois/duas change depending on the noun they modify. Example: um carro, uma casa, dois livros, duas cadeiras.
Multiples of ten and hundreds
After 20, Portuguese builds numbers by combining tens and units, similar to English in many ways.
30 trinta
40 quarenta
50 cinquenta
60 sessenta
70 setenta
80 oitenta
90 noventa
100 cem / cento
200 duzentos / duzentas
300 trezentos / trezentas
400 quatrocentos / quatrocentas
500 quinhentos / quinhentas
Usage note
Use cem for exactly 100 and cento when combining with other numbers (cento e cinco = 105). Hundreds and thousands also agree in gender when used as adjectives: duzentos reais, duzentas folhas.
Thousands, millions, and large numbers
Thousands and millions are useful for prices, distances, and population figures.
1.000 mil
2.000 dois mil
1.000.000 um milhão
2.000.000 dois milhões
Formatting numbers in Brazil
Brazilian numeric formatting uses a comma as the decimal separator and a period for thousands. Example: 1.234,56 means one thousand two hundred thirty-four reais and fifty-six centavos. This matters when reading prices, receipts, or financial forms.
Money: reais and centavos
Understanding currency terms helps with shopping, dining, and transport.
Real (plural reais) is the currency. Centavo is the subunit.
Examples:
Quanto custa este suco? — Três reais e cinquenta centavos.
Price on a menu: R$ 3,50
Posso pagar com cartão? — Sim, até cem reais sem senha.
Typical sign: Máximo R$ 100,00
Practical phrase bank for payments
Quanto custa? — How much does it cost?
Quanto é? — How much is it?
É R$ 12,00. — It’s twelve reais.
Você tem troco para R$ 50? — Do you have change for fifty reais?
Posso pagar com cartão? — Can I pay with card?
Time and dates
Telling time and understanding schedules are everyday tasks. Brazilian Portuguese uses 24-hour notation frequently, especially for official schedules, but spoken time commonly uses 12-hour style with context.
Horas:
1:00 uma hora
2:30 duas e meia
7:15 sete e quinze or sete e quinze minutos
13:00 treze horas or uma da tarde
Days, months and dates:
segunda-feira, terça-feira, quarta-feira, quinta-feira, sexta-feira, sábado, domingo
janeiro, fevereiro, março, abril, maio, junho, julho, agosto, setembro, outubro, novembro, dezembro
Example: A reunião é dia 12 de abril às 14:30. — The meeting is on April 12 at 14:30.
Phone numbers and addresses
Phone numbers in Brazil often include an area code and can be read in groups. Mobile numbers may have 9 digits after the area code.
Example phone format: (11) 9 8765-4321
How to say it: disca zero onze nove oito sete seis cinco quatro três dois um or simply fale com o número onze, nove, oito sete seis cinco quatro três dois um.
Addresses use numbers for street and building: Rua das Flores, 123, apto 45. Example: Moro na Rua das Flores, número 123, apartamento 45.
Counting in real contexts: practice dialogues
At a bakery:
Cliente: Eu quero um pão e dois doces, por favor.
Padeiro: São R$ 6,50. Você paga em dinheiro ou cartão?
On public transport:
Passageiro: Quanto custa a passagem?
Bilheteiro: A tarifa é R$ 4,40.
Passageiro: Aqui está R$ 5,00. Você tem troco?
At a hotel reception:
Recepcionista: Seu quarto é o 302.
Hóspede: Obrigado. O café da manhã começa às 7:00?
Common mistakes and how to avoid them
1. Gender agreement: Remember that numbers like um/uma and dois/duas must match the noun. Example mistake: um cadeira is wrong; correct: uma cadeira.
2. Decimal and thousand separators: When reading prices, be aware that a comma is the decimal marker. Reading 1.000,50 as a thousand and a half is different from English conventions.
3. Pronunciation of nasal vowels: quinze, dezesseis, and cem have nasal endings that influence sound. Practice listening to native speakers to capture nasalization.
4. Using cento vs cem: Say cem only when the number is exactly 100. For 101 say cento e um, not cem e um.
Mini practice: spot the error
Sentence: Eu tenho dois carteira. Wrong. Correct: Eu tenho duas carteiras.
Sentence: O preço é R$ 1,500.00. Wrong format for Brazil. Correct: O preço é R$ 1.500,00.
Study tips and quick drills
1. Start by memorizing 0–20 and the tens. That covers most small numbers you’ll encounter.
2. Label real items at home with numbers in Portuguese: a porta 1, a janela 2, o livro 3. Read them aloud.
3. Use real receipts, menus, and schedules to practice reading numbers and currency formatting.
4. Drill phone numbers and addresses in the format used in Brazil; practice saying them in natural chunks.
5. Listen to short Brazilian Portuguese audio (radio jingle, weather announcement) and try to write down the numbers you hear.
Useful mini-glossary of numeric expressions
Meia hora — half an hour; usada com horas: duas e meia
Da manhã / da tarde / da noite — in the morning / afternoon / evening; used with times
Agora — now; used with time expressions like agora mesmo or agora às 3
Hoje / amanhã / ontem — today / tomorrow / yesterday; often combined with dates and numbers
Por favor, pode me dar troco? — Please can you give me change? Troco is change (money)
Resources for continued practice
1. Local menus: read and translate prices, then order aloud in Portuguese.
2. Transportation timetables: match departure times and platform numbers to announcements.
3. Grocery receipts: identify item quantities and prices, then calculate totals aloud.
4. Flashcards: make cards for numbers, currency phrases, and time expressions, then test yourself in context.
Conclusion
Numbers are a high-return area for beginner learners of Brazilian Portuguese. Start with 0–20, learn the tens and hundreds, practice currency and time formats, and focus on gender agreement and pronunciation. Use realistic examples like menus, tickets, and addresses to build practical skills quickly.
