An Abelian group (named after the mathematician Niels Abel) is a group where the group operation is commutative. That means that for any two elements a,ba,b of group G,
$a×b=b×a$
Some examples include the integers under addition, the non-zero real numbers under multiplication, and every vector space under vector addition.
A non-example is the set of n×nn×n invertible matrices under multiplication. This set is a group, but, except for the case of n=1, is not an Abelian group because matrix multiplication is not commutative.
