    We prove associativity by first fixing natural numbers a and b and applying induction on the natural number c.. For the base case c = 0, (a + b) + 0 = a + b = a + (b + 0)Each equation follows by definition [A1]; the first with a + b, the second with b.

    In addition, lower differential ratios differentials were usually used in other automatic transmission applications to improve gas mileage (again due to the inefficiency of the earlier automatics, especially when used with small engines). The BW 35 was a more efficient transmission and was quite successful in the US with the smaller engined cars.
