| May 19, 2010 at 12:29 | comment | added | Charles Stewart | How about "For every x∈A, f(x) is prime"? I agree with "avoid", not with "[u]nder no circumstances": the issues are that (i) there's usually poor phrasing going on, and (ii) the typography is tricky. | |
| May 17, 2010 at 2:43 | comment | added | Noah Snyder | I would avoid writing either of Keith's examples. For example "Writing m=[G:H], we see that mG is a subgroup of H" or "When x>0, certainly x^3>0." | |

| May 16, 2010 at 17:47 | comment | added | KConrad | Oh! I did not think those two examples might be sneaky. | |
| May 16, 2010 at 8:22 | comment | added | Torsten Ekedahl | Personally I must admit that both examples would take longer (though far from impossible of course) to parse than versions following Noah's rule. That I think should be the reason for doing it one way or other. (It is very tricky to apply such a principle however as it is very individual. I realised that after having done some programming I tended to put in more parentheses in formulas which probably makes them more difficult to read for some, perhaps most, mathematicians.) | |
| May 16, 2010 at 5:36 | comment | added | KConrad | Writing m = [G:H], mG is a subgroup of H. (Here groups are abelian.) | |
| May 16, 2010 at 5:17 | comment | added | KConrad | When x > 0, x^3 > 0 too. Hmm.. | |
