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
440:. This is fundamentally ill-defined topic. Like all aspects of mathematical aesthetics, designating an identity "remarkable" is a subjective judgment call, and in this case, we've no indication that enough people have collectively made the 398:, in the location D.Lazard suggested. I think this is a good proposal. I disagree with D.Lazard about leaving a redirect, however: I do not believe there is a common English-language meaning for the phrase "remarkable identity". -- 230: 319:"Remarkable" is a common adjective in English; it means "worth noting" or "worth commenting on". In my own papers I have called things "remarkable formulas" but they do not belong in Knowledge under that name. -- 453: 60:. If anyone feels that this is not enough and wants a further merge, you are welcome to place a redirect to the desired merge target and I will undelete the history under it on request. 828: 462:
as a POV fork. "Remarkable" is an inherently subjective description, and the listings here were probably cherry-picked by someone based on their personal opinions of the identities.

under one condition: this should feature more than just what one person thinks are important identities, and should be expanded to be more inclusive if it hasn't been already.

judgment call that we can regard it as a part of the culture. What is "remarkable" about squaring a binomial? Or the fact that squares are nonnegative?

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.--

The formulas in those lists are a good deal less obvious than the ones here, e.g. this list tells you that
