I like to think about it like this: while real numbers in general are impossible to compute, write down or do anything else with them, many statements about real numbers can be expressed in a useful, computable form.
It all gets mind-bendingly mind-bending really fast, especially with people like Harvey Friedman ( https://u.osu.edu/friedman.8/foundational-adventures/fom-ema... ) or the author of this post trying to break the math by constructing an untractably large values with the simplest means possible (thus showing that you can encounter problems that do not fit in the universe even when working in a "simple" theory)
