Basic number building blocks
Start with the core words for tens, hundreds, and thousands. Knowing these building blocks lets you combine numbers quickly and correctly.
cem — 100 (exactly)
cento — used for numbers from 101 to 199
duzentos — 200
trezentos — 300
quatrocentos — 400
quinhentos — 500
seiscentos — 600
setecentos — 700
oitocentos — 800
novecentos — 900
mil — 1.000
milhão — 1.000.000 (singular)
milhões — millions (plural)
How to say 100 and nearby numbers
The word cem is used only when the number is exactly 100. For 101 to 199, use cento plus the rest, connected by space and often peloce with de or e in phrases.
Examples:
100 — cem
101 — cento e um
115 — cento e quinze
120 — cento e vinte
199 — cento e noventa e nove
Note the repeated use of e for and. In Brazilian Portuguese, use e between hundreds, tens, and units, but not between thousands and hundreds when the thousands number is a whole number like dois mil followed by others.
Practical examples with 100
Speaking about money at a store: 100 reais — cem reais
On a receipt: 115 reais — cento e quinze reais
Simple phone message: I will arrive at 1:00 PM — chego às treze horas (note: times don’t use cem)
How to say 1,000 and combinations with thousands
mil is both 1.000 and the base for other thousands. For 2.000 and above, use the cardinal numeral then mil. No plural marker on mil for quantities: say dois mil, três mil, quatro mil, etc.
Examples:
1.000 — mil
2.000 — dois mil
5.000 — cinco mil
10.000 — dez mil
15.200 — quinze mil e duzentos
100.000 — cem mil
Note: when thousands are combined with hundreds and tens, use e between the last hundreds/tens/units only. For example, 2.101 is dois mil cento e um, not dois mil e cento e um.
Practical examples with 1.000
Reading signs: Capacity 1.000 pessoas — capacidade: mil pessoas
Bank balance: I have 3.500 reais — tenho três mil e quinhentos reais
Address numbers: Rua 2.000 — rua dois mil
Simple rules for combining numbers
Follow these practical rules to form larger numbers correctly.
1. Use e between tens and units and between hundreds and the tens/units group. Example: 234 — duzentos e trinta e quatro
2. Do not use e between thousands and the next hundreds when thousands are a discrete number, unless the thousands group ends and the following part needs linking for clarity. Example: 2.300 — dois mil e trezentos is acceptable in speech, but many say dois mil trezentos. Both are widely understood in Brazil. For beginners, learn the simpler dois mil trezentos.
3. Use cem only by itself for 100. Use cento for 101 to 199. Example: 100 — cem, 150 — cento e cinquenta
4. Thousands do not change for plural: always mil after a numeral. Example: one thousand — mil, three thousand — três mil
Common phrases and vocabulary with big numbers
These short phrases show natural contexts where you will encounter or use big numbers.
How much does it cost — quanto custa
It costs 100 reais — custa cem reais
I paid 1.200 reais — paguei mil e duzentos reais
Capacity: 500 people — capacidade: quinhentas pessoas (note agreement: quinhentas for feminine nouns)
Population: 1,000 people — mil habitantes
Price list: 300 g — 300 g — trezentos gramas
Gender and agreement notes
Some number words change to agree with feminine nouns. The most common is 500, which becomes quinhentas for feminine nouns and quinhentos for masculine nouns. Similarly, 200, 400, 600, 800 do not change, but the accompanying noun does (e.g., duzentas páginas). For beginners, match the number ending to the noun gender when possible.
Examples:
500 reais — quinhentos reais
500 pessoas — quinhentas pessoas
200 páginas — duzentas páginas
Common beginner mistakes and quick fixes
Mistake: Saying cento for 100. Fix: Use cem for exactly 100 and cento only for 101-199.
Mistake: Using plural mil. Fix: Do not pluralize mil. Say dois mil, not dois mils.
Mistake: Omitting e too often. Fix: Use e between tens and units and between hundreds and tens/units: 121 — cento e vinte e um.
Mistake: Forgetting gender agreement. Fix: For feminine nouns, change 500 to quinhentas and 200/400/600/800 numerals to their feminine forms when needed (duzentas, quatrocentas, seiscentas, oitocentas).
