Sorry, I do not understand your notation.
Do you perhaps mean the binomialcoefficient C(8,5) ?
That would be
8!
-------
(5!)(3!)
which is
8*7*6
-------
3*2
which is
8*7
which is
56
evaluate
8C5

Damon, back in the olden days, in the days of antiquity when I was teaching that stuff we often used the notation
8C5
and it meant C(8,5)
Some older text book would have used the notation
8P5 to stand for P(8,5)
