Proof step 2 from proof bits2int-rec-false (previous step)

⊦ bits2int(bits + false ') = bits2int(bits) * 2, bits = []

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ bits.first ∧ bits ≠ [] → bits2int(bits) = bits2uint(bits)
Proof step 4:
¬(¬ (bits + false ').first ∧ bits + false ' ≠ []) ⊦ bits2int(bits + false ') = bits2int(bits) * 2, bits = []
Proof step 6:
¬ (bits + false ').first ∧ bits + false ' ≠ [] ⊦ bits2uint(bits + false ') = bits2int(bits) * 2, bits = []

Rule argument

name: bits2int-pos-02 rotate: F subst: [bits] → [bits + false ']
