|Abstract:||We define a quaternion to be an expression a + bi + c.1 + dk, where CL, b, c, el E R, and define addition and multiplication in the natural way with: i2=j2 = k2 = -1 ij= -ji = k jk= -kj= i ki= -ik= j (1) The set of real quaternions forms a skew field or a division ring which fails to be a field because commutativity under multiplication does not hold.|
