Proof step 1 from proof and-rec-08 (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

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

Rule argument

Additional information

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