Wikipedia:Manual of Style/Mathematics says not to use "if and only if" in definitions. Dwelling on trivialities such as a0=0 is only distracting from the main points. It is already clear that a "nonzero x in R" is an element. undo Tag: Undo

curprev 00:4600:46, 15 December 2020‎ Ebony Jackson talk contribs‎ 10,993 bytes −133‎ →‎Examples: The result for K[G] includes the result for K[<g>] as a special case, so it makes sense to simplify by mentioning only the former. The relationship of zero divisors to division rings is not really special to this example, and is mentioned later in the article, so it makes sense to omit this too. undo

The rare person who knows ring theory but does not know what injective means can click on "injective" to find out what it means. undo
