The Vedic Square
The digital roots of the times-tables fold into a 9×9 grid of striking symmetry.
Worked demonstration
In the Vedic Square — a 9×9 grid of the digital roots of the times-tables — what single digit sits where row 2 meets column 2? (Work out 2 × 2, then keep adding its digits until one digit remains.)
Try it yourself
Why it works
Each cell is the digital root (value mod 9, with 9 for multiples of 9) of row × column, producing repeating, mirror-symmetric patterns.
Background & Explore Further
The Vedic Square comes from the 20th-century Vedic Mathematics system (named after — not drawn from — the Vedas). The patterns are ordinary mod-9 arithmetic; explore how digital roots also power 'casting out nines'.
