Re: Finding a mental arithmetric book

Is it by any chance 'Trachtenberg's High Speed Mathematics'?

Re: Finding a mental arithmetric book

Trachtenberg was an engineer who ended up captive in a concentration camp, where he thought about math to avoid going crazy, and I don't know his exact story of when he got out, but he did, and then taught the high speed mental math to others.
I had that book ganesh.  There is a short biography at the beginning.

That's ironic, I normally go crazy thinking about math.
