Proof step 5 from proof bits2int-mklist-01 (previous step)
| ⊦ bits2int((mklist(boolvar, n) + boolvar ') + bits) = bits2int(boolvar ' + bits) |
User applied rule insert rewrite lemma
And obtained the following new goals
- Proof step 6:
⊦ (bits + bits0) + bits1 = bits + bits0 + bits1
- Proof step 7:
⊦ bits2int(mklist(boolvar, n) + boolvar ' + bits) = bits2int(boolvar ' + bits)
Rule argument
seq: ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1
subst: [bits1, bits0, bits] → [bits, boolvar ', mklist(boolvar, n)]
rotate: F
