Today, while flirting with my first HP machine (15C), I had an epiphany: I realized that I almost never use the "division" key. Instead, for some reason which Freud might explain, I will always (at least for any non trivial fraction) first compute the denominator, invert it, and then multiply the numerator.

I don't know why I do it. It just comes natural to me. It may be something wich happens with all RPN nuts, or it may have had an origin when, at the beggining of times, in Calculus classes, I was trying the avoid the need to memorize yet another rule (derivative of a fraction) by forcing the world to be constituted only by multiplying factors.

Question: wich hypothesis is closer to the truth?

Hyp 1: Most RPN/RPL nuts are like this, because this is a disease which develops as a natural consequence of their (our) beloved yoda-speak;

Hyp 2: My kids are right: I am just weird.

BTW: Hypothesis 1, if true, would imply that the arithmetic key placement in HP41, with a seldom used key in such a privileged position, was not a best choice.
