I think you are one of 90% of smart piple.

Just take 1 and 1. Their difference is 0 and product is 1. Also 1.4 * 1.4 != 1

Althougth I think my IQ isn't enough,but I think that in the plural sense ,solve the problem like $$$x^k=1$$$ ,you can make it in the coordinate system ,set the $$$\forall x \in C,x=a+bi(a,b\ in R),i^2=-1$$$ into point $$$(a,b)$$$ ,and change into represented by polar coordinates with,you get $$$(c,d)$$$ which represents the distance and the degree of angle,then $$$(c_1,d_1) \times (c_2,d_2)=(c_1c_2,d_1+d_2)$$$ .So I can do……
