The object of this maths game is to protect Earth from meteors and other space hazards, by using your algebra skills to calculate accurate trajectories for Earth’s surface-to-space missiles.
Unfortunately, you are advised by poorly-educated and argumentative scientists who recommend conflicting trajectory formulae. It is up to you to choose the best formula, and calculate y for x in order to plot waypoints and guide your missile towards its target.
Eliminate all threats and save humanity, using as few missiles as possible.
