Q restricted rewrite system:
The TRS R consists of the following rules:

app2(app2(*, x), app2(app2(+, y), z)) -> app2(app2(+, app2(app2(*, x), y)), app2(app2(*, x), z))

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.

By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

APP2(app2(*, x), app2(app2(+, y), z)) -> APP2(app2(*, x), z)
APP2(app2(*, x), app2(app2(+, y), z)) -> APP2(app2(*, x), y)
