% 0.22/0.42 % SZS output start Proof
% 0.22/0.42 Axiom 1 (monotony_lub1): multiply(X, least_upper_bound(Y, Z)) = least_upper_bound(multiply(X, Y), multiply(X, Z)).
% 0.22/0.42 Axiom 2 (monotony_lub2): multiply(least_upper_bound(X, Y), Z) = least_upper_bound(multiply(X, Z), multiply(Y, Z)).
% 0.22/0.42
% 0.22/0.42 Goal 1 (prove_p07): multiply(c, multiply(least_upper_bound(a, b), d)) = least_upper_bound(multiply(c, multiply(a, d)), multiply(c, multiply(b, d))).
% 0.22/0.42 Proof:
% 0.22/0.42 multiply(c, multiply(least_upper_bound(a, b), d))
% 0.22/0.42 = { by axiom 2 (monotony_lub2) }
% 0.22/0.42 multiply(c, least_upper_bound(multiply(a, d), multiply(b, d)))

% 0.22/0.42
% 0.22/0.42 RESULT: Unsatisfiable (the axioms are contradictory).
