About QuickCalculation

QuickCalculation is a math game built around the four basic operations. You solve number puzzles as quickly as you can, testing your reaction speed and your ability to work through the operations in reverse.

Number puzzles

Each game generates new puzzles. A puzzle can be solved using different operations, and each operation awards a different score, so your choice affects how many points you earn.

Tools and art

You can upgrade in-game items to make the game easier. Its hand-drawn art style is designed for players of all ages.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
