[math-fun] There must be something wrong with Mathematica's Round function--
It has no effect on this 4th Grade homework problem: "Estimate: Workers in Italy receive an average of 42 vacation days per year. Workers in the United States receive an average of 13 vacation days per year. Explain how to use rounding to estimate how many more vacation days workers in Italy receive each year." --rwg Another nice one: "Write 47,000 in expanded form." I suggested forty-seven Ms. This is a private school. Everybody says parTISSiple.
Maybe try submitting it to Deep Thought ... Oh, wait --- you already did! WFL On 12/4/13, Bill Gosper <billgosper@gmail.com> wrote:

Heh, easy: Italians get around a month more vacation.
Oops, logophagy time. Docfiend NeilB points out: In[5]:= Round[42, 10] - Round[13, 10] Out[5]= 30 is almost certainly the question's intent. --rwg On Tue, Dec 3, 2013 at 11:12 PM, Bill Gosper <billgosper@gmail.com> wrote:

Give that man a silver star. Otherwise it looks like the whole math-fun list would have had to resit ... WFL On 12/6/13, Bill Gosper <billgosper@gmail.com> wrote:

The question still seems likely to confuse 4th graders. "How to use rounding to estimate ..."? What would the kids say if we gave them almost the exact same problem immediately afterwards, but added 2 days to both the United State and Italy numbers. I'm sure they'd expect the estimate of the *difference* to remain the same... On 2013-12-05 17:49, Bill Gosper wrote:

The meaning and purpose of life is to give life purpose and meaning. The instigation of violence indicates a lack of spirituality.
