0 < 52429 * j + 2 * i0, 524288 ≤ 52429 * j + 2 * i0, 0 ≤ 52429 * j + 2 * i0, i0 * 10 + j ≤ 65536, 0 ≤ i0, 0 ≤ j, 26214 ≤ i0, j ≤ 9, 0 < i0 ⊦

User applied rule cut formula

And obtained the following new goals

Rule argument

fma: 26214 * 10 + j ≤ i0 * 10 + j

Additional information

Used simplifier rules: ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i;% ⊦ i + j ≤ i0 + j ↔ i ≤ i0;% ⊦ 0 < i ∧ 0 ≤ j → ((* j) ≤ (* i) * i0 ↔ (i + j - 1) / i ≤ i0);%i0 ≠ 0, i0 ≤ i ⊦ (* i) ≤ j → (* i0) ≤ j;% ⊦ i * j * j0 = (i * j) * j0;% ⊦ i * j = j * i; Used formulas: 26214 * 10 + j ≤ i0 * 10 + j
