Defination / Uses

A combination in mathematics is a selection of items from a collection where the order of selection is irrelevant (unlike permutations).

The act of selecting items from a collection in such a way that the order in which they are chosen is irrelevant. Combinations of those numbers refer to the number of different groups that can be formed by picking some or all of the components. Combinatorics is an area of mathematics that includes both permutations and combinations. Combinations and permutations are not the same as rounding and midpoint.
