| Jun 10, 2010 at 9:33 | comment | added | Pietro | Just this week I graded a paper where a student started out with a 3x3 matrix with 2 repeated rows, very resourcefully did some row operations including division by 3, used rounding from a calculator, and managed to find an inverse for the original matrix... I had to go back to find out what the mistake was! | |

I like to emphasize that someone must write all that magic software that makes the world go round, and it may well be them. Students nod sagely. Some of them later become programmers... | |
