While your original question was about dealing with floating point
round-off errors, I responded to that question in a different message.
In this message, I was responding only to your reaction to discovering
the use of algebra in David Goldberg's article.

> ...learn algebra? career? you assume too much

No, I was rather careful to write my message to avoid making those
assumptions; I didn't assume you were planning a technically-oriented
career - I merely advised against pursing one if you found algebra too
difficult. I didn't assume that you'd already tried and failed to learn
algebra, I deliberately worded it to be equally appropriate whether or
not you'd tried to learn algebra yet.

I did assume that you needed to learn algebra to correctly understand
propagation of error. Only the very simplest concepts in that subject
can be explained without it; not enough to be useful, just enough to be
dangerous.
