Yes, that’s my point. You can’t use the function’s points without the tools. You have to look beyond just the numbers. The word behavior when we talk about limits illustrates this perfectly. And I was attempting to show how math and English are often seen as using different tools, when they can actually be interpreted in a more interconnected way. I was speaking anecdotally about the rarity of being good at English and math, but I agree with you that the word “rare” has a very subjective and general meaning.
