Proof step 10 from proof ac-dups-03 (previous step)

⊦ addclass(class1, (sk × val) ' + fis1 + (sk × val0) ' + fis0, st) = addclass(class1, (sk × val) ' + fis1 + fis0, st)

User applied rule structural induction

And obtained the following new goals

Proof step 7:
⊦ addclass(class1, (fs ' × val) ' + fis1 + (fs ' × val0) ' + fis0, st) = addclass(class1, (fs ' × val) ' + fis1 + fis0, st)
Proof step 8:
⊦ addclass(class1, fis + (i ' × val) ' + fis0, st) = addclass(class1, fis + fis0, st)
Proof step 9:
⊦ addclass(class1, (i ' × val) ' + fis, st) = addclass(class1, fis, st)

Rule argument
