Counting 70–99

In France, seventy is expressed as sixty-ten and numbers up to seventy-nine continue by adding units to sixty; in Belgium and Switzerland, seventy is simply seventy and numbers follow straightforward additions.

Eighty is quatre-vingts (four twenties) in France and this form is used for eighty-eight etc.; in Belgium and Switzerland, quatre-vingts remains standard while Switzerland allows huitante.

In France, ninety is seventy-ten plus units (soixante-dix plus numbers) while Belgium and Switzerland use nonante followed by simple additions; this makes Belgium/Switzerland forms more regular.

France uses soixante-dix and quatre-vingts forms while Belgium and Switzerland prefer septante, huitante, and nonante for more regular counting; choose your regional style and practice with examples to internalize the pattern.
