The subject of this article is not a thing: the collection of trivial algebraic identities discussed here is not treated as a single topic in any sources, and is certainly not treated under the name "remarkable identities". The place one might find such a list is a textbook on algebra (perhaps in

this looks like a collection of identities that one person found helpful or useful, which isn't an encyclopedic topic. If done properly, with a list of all algebraic identities which have been listed in an external source or have received some discussion from mathematicians, it would be extremely

could be beefed up a bit with some of these, but a full merge would be going overboard. I do not think that a redirect is appropriate in this case.--
