Proof step 29 from proof bitsand-cast-04 (previous step)

# bits0 < # bits1, # bits1 ≤ # bits0 + n0 ⊦ sgn(bitsand(mklist(boolvar, n0) + boolvar ' + bits0, false ' + bits1)) = sgn(bitsand(boolvar ' + bits0, false ' + bits1)), n0 = 0, bits1 = []

User applied rule cut formula

And obtained the following new goals

Proof step 30:
boolvar, # bits0 < # bits1, # bits1 ≤ # bits0 + n0 ⊦ sgn(bitsand(mklist(boolvar, n0) + boolvar ' + bits0, false ' + bits1)) = sgn(bitsand(boolvar ' + bits0, false ' + bits1)), n0 = 0, bits1 = []
Proof step 33:
# bits0 < # bits1, # bits1 ≤ # bits0 + n0 ⊦ boolvar, sgn(bitsand(mklist(boolvar, n0) + boolvar ' + bits0, false ' + bits1)) = sgn(bitsand(boolvar ' + bits0, false ' + bits1)), n0 = 0, bits1 = []

Rule argument
