Consider the direct product of Z2 with Z3, Z2 × Z3. Define the two binary operations as follows: (а, b) @ (с, а) (а, b) 8 (с, d) (а +2С, b +3 d), (а -2 С, b ез d). ie, addition modulo 2 and modulo 3, multiplication modulo 2, and modulo 3, respectively. (Hint: Enumerate the elements of this set.) Prove or disprove that Z2 x Z3 is a field.
