This actually leads to one other concern we should address: this tutorial will

assume that you have basic familiarity with the command line. Rust does not
require that you know a whole ton about the command line, but until the
language is in a more finished state, IDE support is spotty. Rust makes no

We don't want to take the inverse of zero, so we check to make sure that we
weren't passed one. If we weren't, then we return an `Err`, with a message. If
