Proof step 10 from proof shiftright-byte-8-pos-01 (previous step)

¬ 2 ^ j ≥ 128, 0 ≤ j, 0 < j, 0 ≤ b2i(by), 8 ≤ j, 2 ^ j ≤ b2i(by) ⊦ b2i(by) / 2 ^ j = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
0 ≤ j, 0 < j, 0 ≤ b2i(by), 8 ≤ j, 2 ^ j ≤ b2i(by), 2 ^ j < 128 ⊦ b2i(by) / 2 ^ j = 0

Rule argument
