Arithmetical Operations

The results of arithmetical operations have different visual effects that are independent of prime numbers.

In summary:

1. Sums: n + m
   • “DIAGONAL Sums”
   • PRIMES as “Diagonal Sums”
2. Products: n x m
   • “ORTHOGONAL Products”
3. Sums of Powers of 10 plus Digits: n x 10 + m
   • “DIGITO-DECIMAL” or “DIGITAL” Sums
4. Sums of Squares in Triangles: n² + m²
   • Pythagoras’ a² + b² = c²
   • c = SQRT (a² + b²) or as a new format:
5. Sums of Squares in “OCTAGONS”
   • Roots of Sums of Squares as “DIAGONALS”
6. Sums of Squares plus Roots: n² + m
   • “MULTI-DIMENSIONAL Sums” [2D + 1D]

“Digital” Sums are as new a concept as “Octogonal” and “Multi-Dimensional” Sums – all thanks to the advent of software as ‘thinking aids’.

And here as ‘viewing aids’:

1. “DIAGONAL Sums“: n + m

2. “ORTHOGONAL Products”: n x m

3. “DIGITO-DECIMAL” or “DIGITAL” Sums: n x 10 + m

4. Pythagoras’ Sums of Squares in Triangles: n² + m²

5. Pythagoras’ Roots of Sums of Squares: SQRT (n² + m²)

6. “MULTI-DIMENSIONAL” Sums: n² + m
