This is a math game for Android and iOS that teaches the concept of Digital Root (DR) in a fun way. Digital Root involves adding the individual digits of any number greater than 9 in one or more consecutive steps until it is reduced to its single digit value (1 to 9). For example, the Digital Root of 59 is 5, derived as shown here: 59 = 5+9 =14, 1+4 =5. The Digital Root principle can be utilized by school children to quickly verify answers to mathematical problems (www.ferndez.com.au/howtouse.html).
