Operator overloading page

1. If the idea is to teach operator overloading, I don't know why he does it with such complicated examples.

2. What does zip() mean in the Term class?

I agree this is perhaps needlessly convoluted, especially if we don't need to be building up the class step by step. It would be easier to show the whole class definition and then point out which part allows which functionality.

More generally, however, it might be better to just

• start with examples of overloading (1 + 2, 1.0 + 2.0, 1 + 2.0, "con" + "cat", [2] 3, "a" 5)
• then say you might want to do it for your own classes (mention the symbolic algebra example here? but not sure - perhaps another example, or none)
• mention specific methods that it may be useful to implement, and their effect

Also: "__getitem to apply [1] to your object" -> rephrase for clarity ("__getitem to let you index or access part of your object like a sequence or dictionary, e.g. newObject[1] or newObject["data"]")
