comment Find the sum of all the multiples of 3 or 5 below 1000
The first two sums account for multiples of $3$ and $5$, the last sum accounts for over-counting multiples of $15$ (which can appear in either of the first two sums).

comment Two-term Binomial-Bernoulli Transform
That's great. Presumably, infinitely many such transforms follow from two generating functions $E$ and $F$ such that $EF = 1$.
