The set H of quaternions is defined as follows: -{[- H = c+di +di]: a,b,c,d€R}. a+bi -c+di a - bi Prove that H is a subring of M2x2(C). Then prove that H is a non-commutative ring with identity in which every nonzero element has a multiplicative inverse. (Such rings are called division rings or skew fields. They differ from fields only in the fact that their multiplication operation is not required to be commutative.)
