Let V1 = < {a1, a2}, max> and V2 = < {b1, b2}, min> is the two number system, where max (x, y) represents the x and y, the larger number min (x , y) represents the x and y in the smaller number. max and min can be seen as a binary operator. Enter a1, a2, b1, b2 is an integer, consider the product algebra V1 V2. (1) Let plot algebra binary operation is* operation, the output of its operation table (2) units of output product algebras and $ nil
