So it’s actually further down on the building block tree than prime numbers
Prime Numbers are the building blocks of Mathematics...What is that supposed to mean?

So it’s actually further down on the building block tree than prime numbers

It could reasoned that Prime Numbers are the real compute-er
With the natural numbers, n, and m. n can be measured m times.
So I suppose they are the building blocks of Math.
1, -1, i, -i, +/-1+/-i, as well as 0 are the true fundamental numbers of Mathematics.
And any natural number n, can be measured as (1+1...n times).
Excluding 0, all the fundamental numbers in the 1st paragraph are simple derived from 1.
