## Introduction

Many moons ago, I started a ridiculous quest to solve every Project Euler problem, in order, with a different programming language. I called it âheteroglotâ.

Partway through that, I gave myself the additional unwritten rule that the next language would be selected by polling the nearest group of nerds. This has resulted in math problems solved in such wildly inappropriate languages as vimscript, MUMPS, LOLcode, and XSLT.

Itâs been a while since I did one of these, but I still remember that the next language Iâm stuck using is COBOL. I donât know who suggested it, but I hope he chokes on a rake.Â â„

I figure if this is interesting to me, it might be interesting to someone else. So letâs learn some math and/or COBOL.
