It was a great find. I hate Printing and filling out forms using pen is so old school and requires extra step of scanning everything back in. It was also Free! Adobe is way too expensive for the handful of times a year I would need it.

active oldest votes. 5. The symbol (NK) is read as “n choose k.” It represents the number of ways to choose k objects from a set of n objects.
To calculate combinations, we will use the formula NCR = n! / r! * (n — r)!, where n represents the total number of items, and r represents the number of items being chosen at a time. To calculate a combination, you will need to calculate a factorial.
In mathematics, a combination is a selection of items from a collection, such that (unlike permutations) the order of selection does not matter.
Remember, the formula to calculate combinations is NCR = n! / r! * (n — r)!, where n represents the number of items, and r represents the number of items being chosen at a time. Let's look at an example of how to calculate a combination.

In mathematics, a combination is a selection of items from a collection, such that (unlike permutations) the order of selection does not matter.
One could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P(n, r)=n!(NR)!
The difference between combinations and permutations is ordering. With permutations, we care about the order of the elements, whereas with combinations we don't. For example, say your locker combo is 5432. If you enter 4325 into your locker it won't open because it is a different ordering (aka permutation).
