Proof step 44 from proof int2bytes-first-zerobyte-01 (previous step)

j0 + 8 * i0 = 1, 0 < i0, 0 ≤ j0, j0 < 8 ⊦ i0 = 0, 8 * i→n(i0) = 1, i→n(j0) + 8 * i→n(i0) = 0, j0 = 1

User applied rule insert spec-lemma

And obtained the following new goals

Rule argument

seq: i * j + j0 = i0 * j + j1, 0 ≤ j0, j0 < j, 0 ≤ j1, j1 < j ⊦ i = i0 ∧ j0 = j1 subst: [i, j, j0, i0, j1] → [i0, 8, j0, 0, 1] rotate: F spec: int-mult inst: name: modeqp

Additional information

Used simplifier rules: ⊦ i * j = j * i;% ⊦ i + j = j + i; Used terms: i0, 8, j0, 0, 1
