as most of these discussion they go from "these number are impossible!" to "but wait! there's algebra!" without really providing a framing context of what's going on.

this is what's going when the article say "slides smoothly in toward 2"

and this is another common example, which "slides" toward a different number (which is why when you see the division alone is "undefined" and only acquires value in context)

https://www.google.com/search?q=sin(x)/x

but beyond the "just apply limits" party trick it's the implication however that's the most interesting part, and I'll use the words from here[1]:

> Things that appear to be zero may be nonzero in a different dimension (just like i might appear to be 0 to us, but isn’t)
