Where appropriate, I've included a link to an example of each step. These are mainly from Liqupa, a language I have been working on myself for some time. These examples are reasonably complex and are provided so you can see how to format your work and get an idea what a complete answer might look like. Please feel free to use them for guidance and clarification, but create your own system at each step. At some points, I've included a " Just let me see your data" link for those of you who would rather see the data and figure out the rules for yourselves before reading explanations and examples.
