When where french numbers made?

French numbers, like those in many languages, evolved over time rather than being created at a specific moment. The system of counting in French is rooted in Latin, with significant influences from the Celtic languages. The modern French numeral system began to take shape around the 10th century, becoming more standardized by the 15th century. The unique counting system, especially for numbers like 70 (soixante-dix) and 90 (quatre-vingt-dix), reflects a historical blend of linguistic influences.
