Learn Portuguese (Portugal): A nossa casa é velha, tem sessenta e cinco anos. - Our house is old, it is sixty-five years old.

In Portuguese, you combine the tens and the units using e (and). So, 65 is literally sixty and five: sessenta (sixty) plus e (and) plus cinco (five). This pattern is used for all numbers from 31 to 99.

Why does it say tem (has) instead of using a verb for "is" to talk about the house's age?

In English, we say someone or something "is" a certain age. In Portuguese, we use the verb ter (to have) for age. You are literally saying that the house "has" sixty-five years.

Why is there an A before nossa casa?

In European Portuguese, it is standard to put a definite article (like o or a, meaning "the") before a possessive word. Since casa is a feminine noun, we use A nossa instead of just nossa.

Why is the word for old spelled velha instead of velho?

Adjectives must match the gender of the noun they describe. Because casa (house) is a feminine word, the adjective for old changes from its default masculine form velho to the feminine form velha.

Why doesn't the second part of the sentence say ela tem (it has)?
