400 is an even number. In Portuguese-speaking environments, 400 is the kind of number you'll hear and need to use regularly, from market prices to building floor numbers.
Mastering numbers like 400 is one of the most practical skills when learning Portuguese. Unlike vocabulary that only applies in specific contexts, numbers come up constantly — in shops, on public transport, in conversations about time and money, and when meeting new people.
Learning Numbers in Portuguese
What makes Portuguese numbers challenging
Gender affects not just 1 and 2 but all the hundreds (duzentos/duzentas, trezentos/trezentas, etc.), requiring you to know the gender of what you are counting. The billion/trillion difference between Brazilian and European Portuguese is a massive trap in financial contexts. European Portuguese pronunciation heavily reduces unstressed vowels, making numbers sound very different from the clear Brazilian pronunciation that most textbooks teach. The 'e' (and) connector between parts of compound numbers can be swallowed in fast speech.
Tips for learning Portuguese numbers
Learn whether you will primarily encounter Brazilian or European Portuguese — the pronunciation differs significantly. Master the masculine forms of gendered numbers first (um, dois, duzentos) as a baseline. Practice with prices — Portuguese and Brazilian currency amounts give excellent real-world number exposure. The 'e' connector in compound numbers is consistent and helps you segment long numbers. Listen to Portuguese-language media to train your ear for the specific dialect you need.
