Proof step 14 from proof test-sqrt-01 (previous step)

¬(144 % 10 = 0 ∧ 2 ≠ 0 ∧ 144 ≠ 0), even(abs(2)) ⊦ mkDecimal(sqrt(144), abs(2) / 2) = mkDecimal(12, 1)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 15:
⊦ sqrt(144) = 12

Rule argument

Additional information

Used simplifier rules: even-2: ⊦ even(2); from specification int-min%eq-same: ⊦ mkDecimal(i, j) = mkDecimal(i0, j) ↔ i = i0; from specification decimal
