div(X, e) → i(X)
i(div(X, Y)) → div(Y, X)
div(div(X, Y), Z) → div(Y, div(i(X), Z))
With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:
POL(div(x1, x2)) = 1 + 2·x1 + x2
POL(e) = 2
POL(i(x1)) = 2·x1
div(X, e) → i(X)
i(div(X, Y)) → div(Y, X)
div(div(X, Y), Z) → div(Y, div(i(X), Z))
