“DIAGONAL Sums”

Geometrically, Sums appear in diagonal positions of cells in a spreadsheet.

Arithmetically, Odd and Even SUMMANDS result in Odd and Even SUMS.

Arithmetically, the Odd and Even characteristics of the Summands determine the Type of Sum resulting: ODD + ODD = EVEN and ODD + EVEN = ODD

EVEN + EVEN Summands = EVEN and EVEN + ODD Summands = ODD

Yet the diagonal nature of “Digital Visualisation” remains – no matter whether the contributing summands or the resulting sums are odd or even.
