Proof step 2 from proof square-le-one (previous step)

0 < i ⊦ sqrt(i) ≤ 1 ↔ i < 4

User applied rule cut formula

And obtained the following new goals

Proof step 3:
i < 4, 0 < i ⊦ sqrt(i) ≤ 1 ↔ i < 4
Proof step 11:
0 < i ⊦ i < 4, sqrt(i) ≤ 1 ↔ i < 4

Rule argument

fma: i < 4

Additional information

Used formulas: i < 4
