A(n,p) = n!/(n - p)!
A(5,3) = 5!/2! = 5*4*3 = 60
A(6,5) = 6!/1! = 720
A(7,3) = 7!/4! = 7*6*5 = 210
A(10,7) = 10!/3! = 604800
A(6,4) = 6!/2! = 360
A(5,3) + A(6,5) - A(7,3) = 60 + 720 - 210 = 570
A(10,7)/A(6,4) = 604800/360 = 1680
570 - 1680 = -1110
A(n,p) = n!/(n - p)!
A(5,3) = 5!/2! = 5*4*3 = 60
A(6,5) = 6!/1! = 720
A(7,3) = 7!/4! = 7*6*5 = 210
A(10,7) = 10!/3! = 604800
A(6,4) = 6!/2! = 360
A(5,3) + A(6,5) - A(7,3) = 60 + 720 - 210 = 570
A(10,7)/A(6,4) = 604800/360 = 1680
570 - 1680 = -1110
