Proof step 2 from proof align-down-app-left (previous step)

# buf0 % EB_PAGE_SIZE + # buf1 < EB_PAGE_SIZE ⊦ (buf0 + buf1).align↓ = buf0.align↓

User applied rule apply lemma

And obtained the following new goals

Proof step 3:
⊦ (buf0 + buf1).align↓ = buf0.align↓ ↔ # buf0 % EB_PAGE_SIZE + # buf1 < EB_PAGE_SIZE

Rule argument

spec: <toplevel> name: align-down-app-same seq: ⊦ (buf0 + buf1).align↓ = buf0.align↓ ↔ # buf0 % EB_PAGE_SIZE + # buf1 < EB_PAGE_SIZE subst: [buf0, buf1] → [buf0, buf1]

Additional information

Used terms: buf0, buf1
