Proof step 3 from proof byte-law-mult (
previous step
)
⊦ i2b(b2i(i2b(i)) * j) = i2b(b2i(i2b(i)) * b2i(i2b(j)))
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 4
:
⊦ i * j = j * i
Proof step 5
:
⊦ i2b(j * b2i(i2b(i))) = i2b(b2i(i2b(i)) * b2i(i2b(j)))
Rule argument
seq: ⊦ i * j = j * i subst: [j, i] → [j, b2i(i2b(i))] rotate: F spec: int-mult inst: name: commutativity
Additional information
Used terms: j, b2i(i2b(i))
