WTF, why wasn't I shown this at school!?!?!
Readers added context they thought people might want to know
This is not a true or general math method for square roots. Adding digits then subtracting 2 only coincidentally works for select perfect squares (e.g. 64, 289) but fails for most others like 16 (gives 5, not 4) or 144 (gives 7, not 12). doubletorus.substack.com/p/why youtube.com/watch?v=AEgGfp… youtube.com/watch?v=8932x_…
