The Unmultiply Game

Stage: 2, 3 and 4 Challenge Level:

Unmultiply is a game of quick estimation. You need to find two numbers that multiply together to something close to the given target - fast! 10 levels with a high scores table.

Time to Evolve

Stage: 4 Challenge Level:

How many generations would link an evolutionist to a very distant ancestor?

Back Fitter

Stage: 4 Challenge Level:

10 graphs of experimental data are given. Can you use a spreadsheet to find algebraic graphs which match them closely, and thus discover the formulae most likely to govern the underlying processes?
