Digital Roots of Numbers

13th Oct 2020
The digital root of a natural number in a given number base is the (single digit) value obtained by an iterative process of summing digits, on each iteration using the result from the previous iteration to compute a digit sum. The process continues until a single-digit number is reached.   Confused?   Let's just hand over to Primary 7 to explain properly! Grab your pencil, paper and rubber! Listen carefully adults!   It's #MathsWeekIreland
