Can you provide more info about the source of this idiocy? I believe that most of the idiocies found in implementations of Common Core come from implementers of the standards, not the standards themselves. Jim Propp On Tuesday, April 26, 2016, Bill Gosper <billgosper@gmail.com> wrote:

"Answer": c. Has anybody ever seen this usage of "the distributive law"? This is from the same Common Core idiots who outlaw "improper" fractions. They also insist that parens enclosing parens be changed to square brackets. --rwg _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com <javascript:;> https://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
