What is a number?
Why does “a” thing have to be continuous within itself?
The number ‘one’/’1’ means a ‘continuity’. One of anything is a continuity of something, within it. One physical entity is a sameness in something of that thing, within it. (Conversely continuity is ‘one’/’1’).
Thus, any number is a discontinuity of continuities.
3 is 3 discontinuous continuities.
A natural number ‘n’ is n discontinuous continuities.
