Digital Roots

A digital root is when you add up the digits of a number and what it comes to is the digital root, but if the number it comes to is a two digit number you add the digits up again and you keep doing that until you get a one digit number.eg. 15+ 18 = 33 then you add up the 3 and the 3 together that came from the 33 which = 6, which means the digital root is 6.
You can use LOGO to make a pattern of the digital roots which you can see on the next page
