Proof step 1 from proof and-rec-07 (conclusion)

⊦ bitsand(boolvar ' + boolvar0 ', bits0 + boolvar1 ' + boolvar2 ') = bitsand(boolvar ', bits0 + boolvar1 ') + (boolvar0 ∧ boolvar2)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ bitsand(boolvar ' + boolvar0 ', bits0 + boolvar1 ' + boolvar2 ') = bitsand(boolvar ', bits0 + boolvar1 ') + (boolvar0 ∧ boolvar2)'

Rule argument

Additional information

Used simplifier rules: ⊦ bits + boolvar = bits + boolvar ';
