Agreement
CEFR B1
Agreement of numeral adjectives
"Vingt" and "cent" take an -s when they are multiplied and not followed by another number. "Mille" is always unchanged.
Vingt and cent take -s if they are multiplied AND end the number. Mille never takes -s.
Examples

Key word(s): vingts
4 x 20, not followed by another number, so it takes -s.
Quatre-vingt-deux élèves.

Followed by "deux", so no -s.
Trois cents pages.
Key word(s): cents
3 x 100, not followed by another number, so it takes -s.
Trois cent vingt pages.

"Mille" is always unchanged.
Common mistakes

Tips to remember
- Vingt and cent: take -s only if multiplied AND last in the number.
- Mille: never takes -s. Never.
- Million and milliard are nouns, so they take an -s in the plural.
