Numbers in everyday life

Numbers 0-100

Portuguese numbers have some key features to remember:

• 1 and 2 have masculine and feminine forms: um/uma, dois/duas
• Numbers from 1-20 have unique forms
• From 21 onwards, use e (and): vinte e um (21)

💬 Example: "Tenho vinte e cinco anos." → "I am twenty-five years old."

Age with "Ter" (To Have)

In Portuguese, you express age using ter (to have), NOT ser (to be):

• Eu tenho 20 anos → I am 20 years old (literally: "I have 20 years")
• Quantos anos tens? → How old are you?

💬 Example: "Ela tem trinta anos." → "She is thirty years old."

This is different from English but similar to French, Spanish, and Italian. Never use "ser" for age!
