• curprev 01:2601:26, 6 December 2022‎ Ebony Jackson talk contribs‎ 18,666 bytes +419‎ The suggestion to be agnostic about whether the group law is notated multiplicatively or additively is a good one. But "closed under operation" does not sound grammatical to me and is not what is commonly said, so I reverted the good faith edit, and instead I spelled out the multiplicative and additive versions separately, which I hope addresses the concern in an even more explicit way. undo
