Please excuse my poor english.

My question might be ... stupid ... but I take a chance
to post it here anyway!

Is it possible to use a package like GSP to do ... algebra?

For example, can we dynamically solve an equation with the
help a tool like GSP??? I know, GSP is for geometry BUT can
we "creatively" use it to do algebra. It would be GREAT for
a student to SEE the resolution of an equation. Is this possible?
If so, how can we do it?

Could we represent the length of a segment with
a "letter" and use the calculator to make all the necessary
(I know this is not possible YET, but can it be included
in a future version???)
We could then represent n^2 like a real square, and dynamically
varying (wash, my english is so bad) the length of the segment "n"
to see the square "expanded". The software would then represent
the area of the square like n^2 and NOT with the "real" number.
We could then represent thing like 2n^2 + n + 3 "geometrically" but
still have an unknow to deal with.
