Project Euler contains a series of interesting problems that might
stimulate one's mathematical and programming skills. Visit it's
website at www.projecteuler.net.
The links below contain solutions to the problems based on
pen-and-paper, Excel, or VB(A).
The solutions are not necessarily the final answer. Rather, they
are a major step towards solving the problem.
Fair warning: if you want to exercise your
own skills first, do so before clicking the links below.
In answering the various questions, I have created a small suite of functions that should prove useful in answering still unanswered questions as well as applications outside of Project Euler. The first set of functions deals with large number arithmetic, i.e., arithmetic for numbers that exceed both Excel and VBA's best precision. Another "library," dubbed the Euler Support library deals with prime numbers, factors of numbers, etc.
Solved in Excel or "by hand." VB(A) solution Uses the Large Number Arithmetic Module Added with the last website update
