Mathematics is useful in strategy games, from backgammon or chess to solving a Rubik’s cube or playing Awale.

Mathematics is useful for preparing budgets.

Virtually everyone uses some mathematical concepts: the builder, the farmer, the merchant, the craftsman, the athlete …

In any Area or Activity:

Mathematics is behind geolocation techniques, from navigation with the stars to GPS.

Mathematics is behind the software of our phones.

Mathematics makes the pension system sustainable.

Mathematics makes realistic animated films.

Will we visit Mars someday? Without math it will never be possible.
