Save Our Dumb Planet - Mangahigh
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.
Slope Dude
Slope dude loves to ski. He teaches us about slope by talking while he skis the course. We learn from him that uphill slopes are positive, Downhill slopes are negative, flat slopes are zero, and vertical “slopes” are undefined.
