You already have a knob you can tweak if you think that "2 a / 3 b" should multiply by b, rather than divide by it. That's a personal choice. Frankly, I'd never touch that knob, because it looks to me like it should divide by b. I agree completely -- in that case, it is natural for b to go in the denominator. The same is true for 1 / 2 * 1000: the meaning of 1/2000 is more natural, mathematically. What Calc does now is clearly correct.
