That is to say, it has, in part, the multiplication table: It is assumed that e1 is the unity or modulus for our algebra, i. e., ele3 = e3et=e3. The multiplication table may, therefore, be written: We assume, moreover, that this algebra has in common with ordinary algebra the property that all its numbers are commutative. In particular, then, e2e3--e3e2 and therefore: It will be shown that the desired algebra has the multiplication table: 2 Cj e2 e3 e2 e2---x aelJt-iae2+ie3 e3 e3 ael+iac2+ie3 bei + ac--ia2--ib)e2+ce3, a, b, c, being any quantities in the domain R(i, i); and also that this algebra is reducible. 2. The Multiplication Table Of The Algebra I. Besides modifying the multiplication table (1) in accordance with the commutative law i. e., introducing the equalities (2) account must be taken of the associative law The associative condition, (3) e2e2, e3=e2, e2e3 II.
