That terrorist, The Mathematician, is at it again. Make sure that you cut the right coloured wires to save everyone!
This involves basic linear graphs, through more-complicated linear graphs to quadratics and non-linear graphs (cubics, reciprocals and exponentials).
My students seem to like this Defuse The Bomb concept, so as Simple Minds said in the eighties, 2 Unlimited in the nineties, and just about any artist since the millennium: if it ain’t broke, don’t fix it.
