I understand the diagnol proof but not a lot of the rest. If you assume only computable numbers exist though a lot of this seems to really not matter.

- lupire 5y agoEven if only computable numbers exist, it's inconvenient, to do math on them in bulk, so it helps to have a set of virtual/potential numbers (misleadingly named the "real" numbers, even though almost all of them (100%) will never be realized in any way).
