## What is Captain Calculus?

Solve a little. Bring home a fortune.

Captain Calculus turns arithmetic practice into a pirate adventure. Choose addition, subtraction, multiplication or division, then pick one of five difficulty islands. Sail an endless trail of levels through four illustrated worlds, with ten problems in each level.

Harder difficulty islands earn more gold. First-try answers earn 10, 25, 50, 75 or 100 gold, with 100 to 1,000 gold for a perfect ten-problem level. A mistake costs only that problem’s reward: retries never take more gold, and every new problem offers a fresh reward at the selected difficulty. Free hints help you work it out at your own pace.

Earned chests collect aboard your ship. Visit the treasure hold, then return to your cave and watch the coins, diamonds and coloured gems spill out through real physics. Your gold stays safe in the cave, with large fortunes stored in labelled gold-bar reserves.

• Addition, subtraction, multiplication and division

• Free visual hints and unhurried practice
