Oh cool, tell me how rounding to the nearest ".5" is working out for you when dealing with dollars? Or one of the many other times in your life you round to something other than a whole number.
And this is why common core is bad. Math is a universal language. Changing it doesn't fix it, it makes you dummmmmmer.
Basic math doesn't say that. Basic math says you can round to the nearest whatever you'd like.Basic mathematics says you only round up at .5 and higher. This travesty is why the system is doomed to fail.
Well, you used to just round to the nearest whole number, be it up or down. .4 and under went down, .5 and higher went up....but that was before the dark times. Before the Empire.
