I am trying to run the LaTeX/SageTeX code presented in John Palmieri answer. The file compiles, but the output PDF is missing all mathematical Sage answers and yet there are no error messages (e.g, no complaint that sagetex.sty or anything else not found).
I am running MiKTeX on a PC and have installed sagetex package. I am wondering what steps I have missed. Do I need additional steps informing MiKTeX of where my Sage is?
