Proof step 27 from proof byte-law-mult-one (
previous step
)
(i0 * 256 + j0) * j = (i0 * j) * 256 + j0 * j, j0 < 256, 0 ≤ i0, 0 ≤ j0 ⊦ i2b((i0 * 256 + j0) * j) = i2b(b2i(i2b(j0)) * j)
User applied rule insert equation
And obtained the following new goals
Proof step 28
:
j0 < 256, 0 ≤ i0, 0 ≤ j0 ⊦ i2b((i0 * j) * 256 + j0 * j) = i2b(b2i(i2b(j0)) * j)
Rule argument
