algebra calculator ...

[Wild Karl-Heinz]

Hi.

I do some mathematics studys at school.
Do validate me homework I don't have
a ruby calculator for algebra.

I would like to have one
Yes I know, I could if I knew what you know,
write my one

It there anything out there do solve
problems like

(a^2b^3c)
---------
(a^2-2)

or just

(2ab^2-c^2)(ab-bc^2)

mybe with describing the steps?

you know what I mean?

regards
Karl-Heinz

The algebra package in the RAA by Shin-Ichiro Hara is *very*
good, but it is probably too high-faluting for you. (It is
really meant for mathematicians. If you don't know what a ring
is, you'll have a hard time using it.) I have a low-faluting
polynomial library called Pnom that can do a fair amount of basic
algebra and which is compatible with the Ruby mathn library,
but I need to implement some good, general, root-finding
algorithms before it is ready for public consumption. It
also might assume a little more math knowledge than what you
are looking for. So I guess you'll just have to write it
yourself .
