comment $e$ to 50 billion decimal places
@Arturo, My point is that the parallelization and vectorizing problem is essentially solved by the mapreduce algorithm. All one needs is a program that calculates some digits, whether in hex or in decimal.

@J.M. I really don't see that. It's a standard map-reduce with key=decimal positions, value=decimal values. The map-reduce framework does the consolidation automatically.

@J.M. Good point, but calculation of the digits of pi and e are easily parallelizable since the calculation of later digits don't depend on earlier ones.

Nice answer, but why do you say that we are not good at parallel computing? Most of Google's services are proof of excellent parallelization.

... or maybe $\binom{A}{2} - 3\binom{B}{2} - 3\binom{C}{2}$

@Rahul: Right, I see that now. So, the solution will be of the form (A choose 2) - 3 (B choose 2)?

I will update the question. (This problem is a part of a larger problem and I forgot the conditions that I'd used.)

Even though both answers are correct, I'm going to mark this answer because it gives me a bit of intuition about what's going. The other answer would have been a better solution to an exam question.
