Robin’s tweets about characteristic polynomials and the Cayley-Hamilton theorem. I suggested looking them up and working through the logic yourself. It’s straight-forward enough and good fun.

CORRECTIONS
– At 07:20 I say 81 when I mean 82. The on-screen number is correct.
– I accidentally say "log troll" instead of "division troll" at 03:38.
– At 03:45 I cross out the wrong 7. Whoops. Gives 117 instead of 171. First spotted by Ryan Parker (no relation).
– I think that’s all. Let me know if you spot any more mistakes.

As always: thanks to Jane Street who support my channel. They’re amazing.
