The numbers 1, 2, ..., 10 are to be entered into the 10 boxes shown below, so that each number is used exactly once:
\(P = (\square + \square + \square + \square + \square)(\square + \square + \square + \square + \square)\).
What is the maximum value of P? What is the minimum value of P?
Not positive
but I think the biggest would be
(1 4 5 8 9 ) ( 2 3 6 7 10) = 756
smallest would be
(1 2 3 4 5 ) ( 6 7 8 9 10) = 600
