toString()
It may seem strange to only define (+,-) without (*,/)... but conceptually things get tricky. 2 kg * 4 kg = 8 kg^2. 2 kg / 4 kg = 0.5 (no unit) These results are computational devices. They are not "masses." What is the return type? kg^2 is used within the context of gravitational attraction, but only as a factor for calculations-- it doesn't have much conceptual meaning. Multiplication might result in a single unit raised to a power or u1 * u2 Division might result in only a `NumericalValue` or u1 / u2. That complexity would make the API difficult to understand; although rigourously correct. This is all very interesting and discussed in: https://en.wikipedia.org/wiki/Unit_of_measurement#Units_as_dimensions and https://en.wikipedia.org/wiki/Quantity_calculus I'm not a physicist and I don't need it, so, punting. :P
