OK, fair enough.

I gather that this is the original meaning of the word "computer", yes.

I'd say it would be good for *every* generation to know how to do this.
Given that it's not exactly complicated, it still astonishes me how many
people cannot do this. I mean, hell, I haven't memorised the
multiplication table, but I know the *algorithm* for all of these
operations.
(I do not, however, know of any way of computing a square root that
isn't horrifyingly torturous...)

Yeah, I know that. I was just trying to inject a little humour.
In spite of the insane popularity of her books, there are apparently a
significant number of people who assert that they aren't very good. (And
not just the radical Christian sects who assert that any magic without
reference to God is the work of Satan...)
