By oversimplifying, these examples actually obscure the lesson. It helped me to think of OOP objects as sub-variables, or even as a set of variables grouped by the first part of their name. Like a "multi-key/multi-value" hash table.

The purpose of functions only started making sense after learning calculus and the replacement method, where a complex term was replaced by a single variable. This is where I learned they're mostly for readability, an adaptation to make programming easier for humans to do.
