Proof step 7 from proof ushort-max-02 (previous step)

256 ≤ i, 0 < i, 0 ≤ i, 0 ≤ j, i * 256 + j < 65536 ⊦ 256 * 256 + j < 65536

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 8:
⊦ i + j = j + i
Proof step 9:
256 ≤ i, 0 < i, 0 ≤ i, 0 ≤ j, i * 256 + j < 65536 ⊦ j + 256 * 256 < 65536

Rule argument

seq: ⊦ i + j = j + i subst: [j, i] → [j, 256 * 256] rotate: F spec: int-basic2 inst: name: add-c

Additional information

Used terms: j, 256 * 256
