Proof step 26 from proof le-abs-numerator (previous step)

0 < j, abs(i) + abs(i) / j < 0, abs(i) / j * j ≤ abs(i) ⊦ i = 0, j = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 27:
⊦ 0 ≤ i ∧ 0 ≤ j → ¬ i + j < 0
Proof step 28:
abs(i) + abs(i) / j < 0, 0 < j, abs(i) / j * j ≤ abs(i) ⊦ i = 0, j = 0, 0 ≤ abs(i) ∧ 0 ≤ abs(i) / j

Rule argument

spec: int-abs name: zero-gs seq: ⊦ 0 ≤ i ∧ 0 ≤ j → ¬ i + j < 0 subst: [j, i] → [abs(i) / j, abs(i)] flags: <all paths>

Additional information

Used terms: abs(i) / j, abs(i)
