Evaluate 10^C6 and 11^P4

These are combinations and permutations.

For 11P4, you multiply 11*10*9*8

You stop when there are 4 numbers. ex: 11P3 = 11*10*9, 11P2 = 11*10

For 10C6, you do same as permutations but then divide by 6!

---> (10*9*8*7*6*5) / (6*5*4*3*2*1)

You can simplify this by cancelling the 5,6,8

---> (10*9*7) / 3
