Giving the problem "in your own words" raises the question of whether or not your restatement constitutes a derivative work.

From the 1976 Copyright Act section 101:

https://www.law.cornell.edu/uscode/text/17/101

> A "derivative work" is a work based upon one or more preexisting works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which a work may be recast, transformed, or adapted. A work consisting of editorial revisions, annotations, elaborations, or other modifications which, as a whole, represent an original work of authorship, is a "derivative work".
