“everyone in the US”, you mean.

]]>This is especially useful when composing functions. A complex function “h” might be the composite of simpler functions “f” and “g”: “h(x) = g(f(x))”. This means that “x” is first given to “f”, which produces an intermediate value, which is then given to “g”. Notice that the flow of data doesn’t match the reading direction. In the alternate proposal, the equation would read “(x)h = ((x)f)g”.

In several branches of mathematics, so called “commutative diagrams” are an important visualization aid. Reversing the traditional notation would help with translating those diagrams to formulas and back.
