Proof step 7 from proof succ-ones (previous step)

∀ bits1. # bits1 < #(bits0 + true ') → true → bits1 +1 = true ' + bitsinvert(bits1) ∨ false ∈ bits1 ⊦ bits0 +1 = true ' + bitsinvert(bits0), false ∈ bits0

User applied rule apply induction

And closed the goal!

Rule argument

subst: [bits1] → [bits0]

Additional information

Used simplifier rules: ⊦ #(bits + bits0) = # bits + # bits0;% ⊦ # boolvar ' = 0 +1;% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ m < n + 1 ↔ ¬ n < m;% ⊦ ¬ n < n;% ⊦ (m + n0) + n1 = m + n0 + n1;% ⊦ m + n = n + m; Used terms: bits0
