First of all, it would be helpful if I knew a way to copy and paste that would preserve the sigma notation or traditional form of what I copy. I hear about latex, but there is no "copy as latex" option. I tried recopying from the browser back into mathematica and I got a non-functional version. I notice everyone else pastes into the nice blue boxes, how do I do that as well? this is an example below
In:= N[!( *UnderoverscriptBox[([Sum]), (n = 1), ((+1) Floor[ *RadicalBox[(49), (2)]])](((((10^((n*2)))) + 1))/((((10^((((((n^2))))*2)))) ((((10^((n*2)))) - 1)))))), (49)*2]
That is what I copy into the browser, and when I recopy from the browser into mathematica I get a non-functional because the little multiply symbols in front of UnderoverscripBox and RadicalBox are highlighted as non-functional. What gives? I'm going crazy because I can't paste and preserve the original form. Help.
