Addition does produce `-0`, but only in `-0 + -0`; it does indeed act as the identity element there. Subtracting is the real weird one, tho: only `-0 - +0` produces -0; every other subtraction of zeros produces +0. Adding +0 to both sides to rearrange the equation, this implies that `-0 = -0 + +0`, but that's not true; that addition produces +0. I think you're right that commutitivity isn't actually the law being broken there; I guess it's additive inverses don't work correctly around zeros (which is why flipping the sign like that isn't guaranteed to work right. -- GitHub Notification of comment by tabatkins Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4718#issuecomment-581639196 using your GitHub account
