% 75.44/75.52 % SZS output start Proof
% 75.44/75.52 The input problem is unsatisfiable because
% 75.44/75.52
% 75.44/75.52 [1] the following set of Horn clauses is unsatisfiable:
% 75.44/75.52
% 75.44/75.52 inverse(double_divide(double_divide(A, B), inverse(double_divide(A, inverse(double_divide(C, B)))))) = C
% 75.44/75.52 multiply(A, B) = inverse(double_divide(B, A))
% 75.44/75.52 multiply(a, b) = multiply(b, a) ==> \bottom
% 75.44/75.52
% 75.44/75.52 This holds because
% 75.44/75.52
% 75.44/75.52 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 75.44/75.52
% 75.44/75.52 E:
% 75.44/75.52 f1(multiply(a, b)) = true__

% 75.44/75.52 inverse(double_divide(double_divide(A, B), inverse(double_divide(A, inverse(double_divide(C, B)))))) = C
% 75.44/75.52 multiply(A, B) = inverse(double_divide(B, A))
% 75.44/75.52 G:
% 75.44/75.52 true__ = false__
% 75.44/75.52
% 75.44/75.52 This holds because
% 75.44/75.52
% 75.44/75.52 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
