Unlike the Small Friend Concept, which is applicable only for Digits smaller than 5, the Big Friend Concept is applicable for all Digits from 1 to 9. The sequence of thinking to be used for Addition or Subtraction of Digits 1 or 2 or 3 or 4 is: See if we have enough lower beads available, if Not, then See if we have the Upper bead available to use Small Friend Concept, if Not, then use the Big Friend Concept. In case of Digits from 5 to 9, there is No Small Friend available. Hence if we don't have enough beads while adding or subtracting a Digit between 5 to 9 on any respective rod, then we directly use the appropriate Big Friend formula. Big Friend is basically the difference between 10 and any of the digits from 1 to 9. Hence the Big Friend for 1 will be 9, for 2 it will be 8, for 3 it will be 7 and so on.
