Proof step 16 from proof int2bytes-rec255-neg (previous step)

i % 256 < 0, i < ~128, i < 0, # int2bytes(i % 256) < 2, i % 256 < ~256 ⊦ (mklist(i2b(~1), 2 - # int2bytes(i % 256)) + int2bytes(i % 256)).rest = int2bytes(i % 256).last '

User applied rule cut formula

And obtained the following new goals

Proof step 17:
~256 = 0 - 256, i % 256 < 0, i < ~128, i < 0, # int2bytes(i % 256) < 2, i % 256 < ~256 ⊦ (mklist(i2b(~1), 2 - # int2bytes(i % 256)) + int2bytes(i % 256)).rest = int2bytes(i % 256).last '

Rule argument

fma: ~256 = 0 - 256

Additional information

Used formulas: ~256 = 0 - 256
