There’s all sorts of magic to be had with numbers, and many mathematicians have made entire careers in finding these little tricks that are mostly useless, but fun anyway. Unfortunately, a lot of calculators are going to truncate the results of this trick, but if you manage to get a hold of one that doesn’t, solving 1/998001 will generate all the three digit numbers from 000 to 999. And in order, no less. If you’re a fan of this kind of math fun, solving 1/9801 will generate all the consecutive two digit numbers.
