Satellite Subtraction is an educational game for the SC-3000 by Pyramid Software. It was only released in Australia as part of John Sands Electronics's Math Blaster series of Educational Software Cassettes
The gameplay is similar to Space Invaders, except with satellites descending to the Earth's surface. The object of the game is to shoot the oncoming satellites by entering the solution to the simple subtraction problem below the satellite. Levels get progressively harder, with more complex equations and faster satellites. The game retains the highest score for competitive play.
