And as for zSprawl, on his order of operations argument and retarded analogy proving absolutely nothing...

You are correct that a specific order of operations in the denominator would be necessary if the denominator still contained an irreducible operation.  But what you failed to realize is that both Day in the numerator of the larger fraction and s in the denominator of the larger fraction are both units of time in different scales, and 1 Day always equals 86400 seconds.  So either time unit contained in the denominators of the smaller fractions can be rewritten to share a time scale with the other, and the larger fraction can be further reduced to a point at which there is no operation remaining its denominator because time can be factored outside of it, hence order of operation restrictions would no longer apply as there are no operations remaining in the denominator of the larger fraction.  Do it if you don't believe me because I know you won't want to.
