Let x0 of type ι be given.
Let x1 of type ι be given.
Apply int_mul_SNo with
minus_SNo x0,
minus_SNo x1 leaving 2 subgoals.
Apply int_minus_SNo with
x0.
Apply Subq_omega_int with
x0.
The subproof is completed by applying H0.
Apply int_minus_SNo with
x1.
Apply Subq_omega_int with
x1.
Apply nat_p_omega with
x1.
The subproof is completed by applying H2.
