Proof step 2 from proof square-eq (previous step)

i * i = j * j ⊦ abs(i) = abs(j)

User applied rule cut formula

And obtained the following new goals

Proof step 3:
abs(i) < abs(j), i * i = j * j ⊦ abs(i) = abs(j)
Proof step 10:
i * i = j * j ⊦ abs(i) < abs(j), abs(i) = abs(j)

Rule argument

fma: abs(i) < abs(j)

Additional information

Used formulas: abs(i) < abs(j)
