( a+ ib)*(C + id) = (ac-bd) + i(ad +bc) since it has iota term we can't say it as positive or negative , so product is always a complex number , it can be either purely real ( ad=-bc ) or purely imaginay ( ac = bd ) or may be having both real and imaginary parts , so it will definately a complex number
