Hehehe, I loved the wonderful mystery of what all those "special"
buttons did, like SIN, COS, LOG, 10^x, SUM, etc.

I also used to love to do a repeated operation and then do as many of
the inverse and see whether the result was the original again. I had
some concept of finite precision :) I also found some calculators
which, when they gave you an overflow error, would allow you to clear
it and continue with the calculation, seemingly with reduced accuracy.

My parents knew not to let me get my hands on a calculator they wanted
to use because I would eventually take it apart. I even once managed
to remove the black epoxy from a chip-on-board package and take out
the die. I must have been about 7 years old. Can't remember how I
managed that - probably prying with a small screwdriver.
