Thank you for the reply, I have proved that the multiplicative holds but I am not too certain what property I should be looking at?

H is a number system where (a,b) belongs in H where a and b is an element of Z(integer) Addition and multiplication are defined as follows: (a, b) + (c, d) := (a + c , b + d) (a, b) x (c, d) := (ac-5bd , ad+bc) For any number (a,b) in H, we can define its norm by ||(a, b)|| :=...
