Proof step 11 from proof sgn-zeros (previous step)

bits0 + false ' = false ' + bits2, ∀ bits. sgn(bits0 + false ' + bits) = sgn(false ' + bits) ⊦ sgn(bits0 + false ' + bits1) = sgn(false ' + bits1), true ∈ bits0

Heuristic quantifier closing applied rule all left

And closed the goal!

Rule argument

pos: left 2 terms: bits1

Additional information

Used simplifier rules: ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1; Used terms: bits1
