Is matrix Abelian group?

The sets Q+ and R+ of positive numbers and the sets Q∗, R∗, C∗ of nonzero numbers under multiplication are abelian groups. The set Mn(R) of all n × n real matrices with addition is an abelian group. However, Mn(R) with matrix multiplication is NOT a group (e.g. the zero matrix has no inverse).
