What's Abelian
?
A group is a set with an binary operation, like multiplication or addition. Let's call this set G. Then, an abelian group has an operation (which we will label as ∙) such that for g,h, any pair of elements in G, g ∙ h = h ∙ g. That is, the operation is commutative, or order doesn't matter. It's named after mathematician Niels Henrik Abel.
