1. Cardinal Numbers


Numbers are very important. Learn them by heart because they are used every day.





  • In Portuguese, the numbers 1 and 2 and from 200 to 900 are feminine (uma, duas, duzentas, trezentas, etc.) when followed by a feminine noun (duas pessoas – two people).
  • Cem is used only for one hundred. Above one hundred, cento is used (101 cento e um, 102 cento e dois, etc.)  
  • In Brazil, when saying ZIP codes or telephone numbers, usually meia (half a dozen) is used for number 6 instead of seis (six). Example: Tel. 2654-0266 (dois, meia, cinco, quatro, zero, dois, meia, meia).   
  • Milhão/Bilhão (million/billion) are masculine and have a plural form (milhões/bilhões). When followed by a noun, the preposition de (of) is required (5 milhões de pessoas – 5 million people).
  • Decimal point (R$ 3.000,00) and not comma (R$ 3,000.00) is used to separate the thousands in Portuguese.

2. Ordinal Numbers


In Portuguese, ordinal numbers can be either masculine or feminine in gender (primeiro/primeira) and singular or plural (primeiros/primeiras) in number. 



Remark: Ordinal numbers are usually used up to 40th, mainly when saying the floor in a high rise building (7ºandar – 7th floor) and also to say the first day of the month (1º de maio – 1st of May).
