If there are n objects to fit r places (e.g. 9 people in 7 chairs, 4 tumblers in a lock) then the number of permutations is nCk, stated as n-choose-k.
This number can be calculated by the formula n!/(n - k)!. If k is equal to n, then (n - k)! = 0! = 1, and the number of permutations is simply n!. If the direction of the permutation is irrelevant (e.g. ABCD is the same as DCBA) then divide by two to cancel out the double-counting.
IF they are math related, write appropriate equations and then apply math rules to solve the equations.

nPr in math stands for permutation :)
Permutation: 8C5 = 56
yes math is debatable.... ex. combination and permutation are very arguable
A permutation is the rearrangement of objects or symbols into distinguishable sequences.You can use the formulas. nPr=n! / (n-r)!where n the set from which elements are permuted and r is the size of each permutation (! is the factorial operator)For example: How many ways can you rearrange the word math? 4P4=4!/(4-4)! 4P4=4!/1 4P4=24
Yes, hit "math", "PRB", "2"
Press MATH and select PRB at the top. The second option, nPr, is permutation. Example: To find P(8,3) type: 8 nPr 3
Different math questions require different methods to solve.

IF they are math related, write appropriate equations and then apply math rules to solve the equations.
P is a permutation. It is asking for the numbers in the ()'s after it. For exapmle, P(6,4) is 6x5x4 which is 120.
