Input TRS:
    1: average(s(x),y) -> average(x,s(y))
    2: average(x,s(s(s(y)))) -> s(average(s(x),y))
    3: average(0(),0()) -> 0()
    4: average(0(),s(0())) -> 0()
    5: average(0(),s(s(0()))) -> s(0())

Direct QWPOS(Pol) ... orients all.
	I(average) = 3 * x1 + 2 * x2	sigma(average) = [2,1]
	I(0) = 3
	I(s) = x1 + 3	sigma(s) = [1]
    PREC: average > 0 > s
