Is there some reason that this topic needed to be created even though the [[divisor]] page already exists? I like nouns referring to objects better than ones referring to relationships, so my preference is that the main page be called [[divisor]]. However the cards fall, I think one of the pages must disappear.[[User:Barry R. Smith|Barry R.

Property 4 is currently: "if a divides b and c then it also divides a+b." Shouldn't the last sum be b+c? If not, then we do not need c, just: if a divides b, then it also divides a+b and a-b and ... Sandy Harris 10:58, 27 June 2009 (UTC)

Topic Already Exists
Is there some reason that this topic needed to be created even though the divisor page already exists? I like nouns referring to objects better than ones referring to relationships, so my preference is that the main page be called divisor. However the cards fall, I think one of the pages must disappear.Barry R. Smith 19:09, 22 July 2009 (UTC)
