In terms of writing or debugging code, I think the limitation is more nuanced than being limited by "series of math-related sentences". It debugging code, it would surely struggle with navigating up and down a stack without losing its train of thought. Consider the following problem. Yes I realize that I'm performing math in these functions but I think that's besides the point. It has to think about what each function does step by step, is the point. Tldr the result is actually 0. https://pastebin.com/raw/RUNPv2RJ The problem isn't that "oh well, a person can't do that in its head, either". The problem is that it's illustrating an incorrect order of operation.
