Proof step 1 from proof ls-add (conclusion)

⊦ dec + mkDecimal(i, j) < mkDecimal(i0, j) ↔ dec < mkDecimal(i0 - i, j)

User applied rule constructor cut

And obtained the following new goals

Proof step 2:
dec = mkDecimal(i1, i2) ⊦ dec + mkDecimal(i, j) < mkDecimal(i0, j) ↔ dec < mkDecimal(i0 - i, j)

Rule argument

var: dec

Additional information

Used simplifier rules: decimal generated by mkDecimal;;
