That still leaves questions that ideally the class should explain: - How does the computer understand that it needs to add - How can the computer go from these 3 lines of text to "sure, let's add" - Why does text even mean anything to the computer - For that matter, sure it can add, but HOW? It's not like it has a pencil and paper. Because indeed the infrastructure between these 3 lines of text and the addition is not trivial. These are legitimate questions.
