Proof step 3 from proof test-div-02 (previous step)

⊦ div(mkDecimal(5, 0), mkDecimal(2, 0), 0) = mkDecimal(25, 1)

User applied rule insert lemma

And obtained the following new goals

Proof step 4:
⊦ dec_j | dec_i → div(dec_i, dec_j, i) * dec_j = dec_i
Proof step 5:
mkDecimal(2, 0) | mkDecimal(5, 0) → div(mkDecimal(5, 0), mkDecimal(2, 0), 0) * mkDecimal(2, 0) = mkDecimal(5, 0) ⊦ div(mkDecimal(5, 0), mkDecimal(2, 0), 0) = mkDecimal(25, 1)

Rule argument

spec: inst: name: div-exact-def seq: ⊦ dec_j | dec_i → div(dec_i, dec_j, i) * dec_j = dec_i subst: [dec_j, dec_i, i] → [mkDecimal(2, 0), mkDecimal(5, 0), 0] flags: current, []
