What is a vedic square?

Answer 1

It's a multiplication table in which every entry is a single digit. If any entry would normally be more than one digit, its digits are added together to make one. For example, 3 x 6 = 18, so the vedic square entry would be 1 + 8 = 9. It was used to create Islamic geometric designs by making a line between entries of the same number.
