Used simplifier rules: ⊦ i + 1 ≤ j ↔ i < j;% ⊦ i ≤ j - i0 ↔ i + i0 ≤ j;% ⊦ i + ~1 = i - 1;% ⊦ i + (* j) ≤ i0 + (* j0) ↔ i ≤ i0 + (j0 - j);% ⊦ i * j = j * i;% ⊦ i ≤ j ∧ j < j0 → i < j0; (forward)% ⊦ 0 ≤ i → j ^ (i + 1) = j ^ i * j;% ⊦ i + j = j + i;% ⊦ i + j + i0 = (i + j) + i0;%i0 ≠ 0, i0 ≤ i ⊦ (* i) ≤ j → (* i0) ≤ j;% ⊦ (* j) ≤ i0 + (* j0) ↔ j - j0 ≤ i0;
