He actually thought I was a maths genius and shouted “Albert Einstein come back” not realising that I just did sqrt(64) in 50 microseconds and then 450 microseconds of schoolboy humour derivation. Probably more like a Feynman approximation than an Einsteinian, but maybe he’ll learn that in decades to come. Good job his pocket calculator couldn’t square 58008 or 5318008 else I probably wouldn’t have grokked it.
