So is there full agreement on what a number is, in the first place? Some would argue that PI is not an actual number; but that it is a concept, like infinity

- marplebot 10y agoA number is also a concept, and there are number systems that include infinities (e.g. https://en.wikipedia.org/wiki/Surreal_number https://en.wikipedia.org/wiki/Surreal_number). It all depends on your definitions/axioms. So in a sense there is not full agreement on what a number is, but several sets numbers are generally agreed upon: integers, rationals, computables, etc.
