Part 6/10:
Numbers that originate from 9 exhibit a unique behavior: every doubling of 9 produces numbers divisible by 9, with vortex sums always reducing to 9. This is expected since any multiple of 9 has a digital root of 9, and the mod 9 operation reflects this property. For instance, 9 doubled is 18; the vortex sum (1 + 8) equals 9, and its modulo 9 calculation gives zero, which is then set to 9 in the ATM of vortex math.
The Power of Modular Arithmetic and Digital Roots
Across all these patterns, the utility of modular arithmetic, especially mod 9, becomes evident. This operation simplifies large numbers by reducing their digital representation to a single digit that retains key properties under multiplication.
