Decimal Discovery

Decimal Discovery is a math game devoted to learning decimals for the Apple II.

There are 3 oil rigs slowly drilling into the substrate below. At the bottom of the screen are 3 different math equations, and the player must choose which oil rig has a correct answer. When the player answers correctly, that equation changes and the drill is reset. A new answer is then placed on each oil rig. The player's goal is to answer as many questions as possible before a drill reaches the bottom of the screen, at which point it's game over. The player can choose to compare, add, subtract, multiply,or divide decimals. They can also choose tenths, hundredths, or thousandths.
