*(x, *(y, z)) → *(otimes(x, y), z)
*(1, y) → y
*(+(x, y), z) → oplus(*(x, z), *(y, z))
*(x, oplus(y, z)) → oplus(*(x, y), *(x, z))

*(1, z0) → z0

### (7) CdtRuleRemovalProof (UPPER BOUND (ADD(O(n^2))) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

*'(z0, *(z1, z2)) → c(*'(otimes(z0, z1), z2))
*'(+(z0, z1), z2) → c2(*'(z0, z2), *'(z1, z2))
*'(z0, oplus(z1, z2)) → c3(*'(z0, z1), *'(z0, z2))
We considered the (Usable) Rules:none
And the Tuples:

*'(z0, *(z1, z2)) → c(*'(otimes(z0, z1), z2))
*'(+(z0, z1), z2) → c2(*'(z0, z2), *'(z1, z2))
*'(z0, oplus(z1, z2)) → c3(*'(z0, z1), *'(z0, z2))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(*(x1, x2)) = [1] + x2
POL(*'(x1, x2)) = x1 + x2 + x1·x2
POL(+(x1, x2)) = [1] + x1 + x2
POL(c(x1)) = x1
POL(c2(x1, x2)) = x1 + x2
POL(c3(x1, x2)) = x1 + x2
POL(oplus(x1, x2)) = [1] + x1 + x2
POL(otimes(x1, x2)) = x1
