Proof step 15 from proof square-le-one (previous step)

0 < i, 0 ≤ i, 4 ≤ i, sqrt(i) ≤ 1, 0 ≤ i → sqrt(i) ^2 ≤ i ∧ i < sqrt(i) +1 ^2 ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 16:
1 < (sqrt(i) + 1)^2, 0 < (sqrt(i) + 1)^2, sqrt(i) ^2 < (sqrt(i) + 1)^2, 4 < (sqrt(i) + 1)^2, i < (sqrt(i) + 1)^2, 0 < i, sqrt(i) < (sqrt(i) + 1)^2, sqrt(i) ^2 ≤ i, 0 ≤ i, 4 ≤ i, sqrt(i) ≤ 1 ⊦
