comment Algebra: sums of rows and columns given, find elements
+1, this is what the mathemagicians used! There used to be number of cards with table of numbers in each one, and just by telling them which cards have your number they would tell you the number!

comment Evaluating $\int \frac{1}{{x^4+1}} dx$
@mixedmath : I like to accept some of the blame, I did not explain the reason, what I said and the way I said it might have come across as unpleasant. I should have said it more gently.
