The answer to the question is -7 and -9.
(i) false;
Let be N = { 0, 1 , 2}; x * y = x + y => a * a = 2a ∈ { 0, 2 , 4}, which is not a( just for a = 0);
(ii) true;
b * c = c * b => a * ( b * c ) = a * ( c * b ); (1)
but, a * ( c * b ) = ( c * b ) * a; (2)
(1) and (2) => <span>a * (b * c) = (c * b) * a.</span>
If my math is correct, it should be 950,000
