Proof step 21 from proof finz-add-bigger (previous step)

#fz(m + 2^ #fz(m)) + n = #fz(m), m + 1 = (2^ #fz(m + 2^ #fz(m)) * 2^ n) * lead(m), (m + 2^ #fz(m)) + 1 = 2^ #fz(m + 2^ #fz(m)) * lead(m + 2^ #fz(m)), odd(lead(m)), odd(lead(m + 2^ #fz(m))) ⊦

User applied rule cut formula

And obtained the following new goals

Proof step 20:
(m + 1) + 2^ #fz(m) = 2^ #fz(m + 2^ #fz(m)) * lead(m + 2^ #fz(m)), #fz(m + 2^ #fz(m)) + n = #fz(m), m + 1 = (2^ #fz(m + 2^ #fz(m)) * 2^ n) * lead(m), (m + 2^ #fz(m)) + 1 = 2^ #fz(m + 2^ #fz(m)) * lead(m + 2^ #fz(m)), odd(lead(m)), odd(lead(m + 2^ #fz(m))) ⊦

Rule argument

[fma-arg: (m + 1) + 2^ #fz(m) = 2^ #fz(m + 2^ #fz(m)) * lead(m + 2^ #fz(m)) ]
