Further my post dt.

(I rarely deal directly with numbers these days, so I do not now recall those tricks much).
I do recall that, many years later (while I was in engineering college, I became known as something of a whiz kid at mental computations AND also at using a slide rule in ways that 'the books' scarcely ever showed. For instance, I read a hint somewhere that the slide rule could be used to help solve quadratics  and I then taught myself how to do that; as well as to do plenty of other quite complex stuff (approximate solutions of differential equations, etc) for various engineering calculations using the slide rule.
Now, I am NOT claiming that I (or any of that group of students who got 'turned on' to computation  and, in my case, to pure math) could ever achieve the 'miraculous' insights and powers of Gauss (or even of much lesser mathematicians).
E.g., recall the two astonishing stories, recounted by Eric Temple Bell in "Men of Mathematics":
i) how Gauss at age 3 was able to discover (through mental computation) an error in his father's computation of the wage bill of a sizable number of workers whom he (the father) supervised; and
ii) how Gauss at age 6 or 7 discovered that a long list of big numbers given to the class to add up were in fact in 'arithmetic progression' (AP); applied the AP formula (which he had worked out on his own, and gave the answer  almost the instant he had been given that problem!].
I do not have access to that book right now, so my retelling of these two minor miracles wrought by Gauss may contain some errors of detail.
Nor, for that matter, do I claim that any of us developed the kind of insights that "Young Archimedes" (Guido? Carlo?? I don't have a copy of that book now) had  as recounted in the beautiful short story of that name by Aldous Huxley. ['Young Archimedes' on his own, age 10 or so, rediscovered the Pythagoras Theorem with no help at all!!!]
I AM claiming that several of us actually learned how to perform 'numerical computations' quite perhaps very  proficiently (and and even to truly enjoy working with numbers)  DESPITE having been entirely turned off by the 'byrote math teaching' to which we had earlier been subjected. (It does appear that a quite sizable number of children who may not be 'good at math' in our conventional school system, do in fact possess quite good math skills).
[I need to make the above clarifications view the distortions and falsehoods, about OPMS for instance, that have been made by one of my critics here. If I do not make such clarification, he may well state that I had claimed I was another Gauss!]
