Playful comparisons

Fun Calculator Pack

A lighter pack for visitors who want to play with numbers without doing tax, mortgages or homework. The calculators still use real formulas, but the questions are pizza, games, movies, parties and space.

Pick a mini mission

Three ways to play with the pack

Each mini mission links a real calculator to a small comparison. It gives the page a reason to be explored instead of scanned once.
