Hi. What is j! ? I know what the PI operator is, but what does
PI[j=1,j!=1..n] do?
I would guess j = 1 to n, excluding j = i.

Sorry to get so close to "off topic" but:
There are persistent rumours that the U.S. Air Force, which has a massive educational

Last vacation I enjoyed reading Jostein Gaarder's "Sophie's World" which is
an engaging and thought-provoking introduction to philosophy presented in
the form of a novel. I can also recommend the following two books on
mathematics and two other books on philosophy.

I assume she intends to move all marks up or down in tandem. I assume too
that the marks themselves are quantitative along some sort of continuum.
Regardless, the easiest thing would be to rank order them and make a decision
where the cutoff lines for A's, B's, etc.make sense. I don't see
