Proof step 4 from proof short-add-min (previous step)

~65536 = ~32768 + ~32768, s2i(sho0) + s2i(sho1) < 0, s2i(sho0) + s2i(sho1) ≤ ~65536 ⊦ s2i(sho0) = ~32768 ∧ s2i(sho1) = ~32768

User applied rule insert equation

And obtained the following new goals

Proof step 5:
s2i(sho0) + s2i(sho1) < 0, s2i(sho0) + s2i(sho1) ≤ ~32768 + ~32768 ⊦ s2i(sho0) = ~32768 ∧ s2i(sho1) = ~32768
