Proof step 3 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 4:
0 < i, i < 4 ⊦ sqrt(i) ≤ 1 ↔ i < 4
Proof step 12:
0 < i ⊦ sqrt(i) ≤ 1 ↔ i < 4, i < 4

Rule argument

fma: i < 4

Additional information

Used formulas: i < 4
