About

Real scenes
Every prompt is grounded in a moment from Lisbon — a tram, a tasca, a tile-lined wall.
Three altitudes
Explorer, Navigator, Architect — pick your level and the math grows with you.
Why it matters
The back of each card explains where the same formula shows up in adult life.

Who it's for

Lisbon Math meets you wherever your relationship with numbers is — whether you're rediscovering them, sharing them, or chasing them deeper.

Students
Teens and university students looking for problems that feel like the real world, not a textbook.
