(ACTIVITY ONE)
(1) A: Find the Digital sum of these
Numbers:
- 18 1 + 8 = 9
- 27 2 + 7= 9
3. 36 3 + 6 = 9
4. 45 4 + 5 = 9
5. 54 5 + 4 = 9
6. 63 6 + 3 = 9
7. 72 7 + 3 = 9
8. 81 8 + 1 + 9
(2) Sometimes you need to add digits more than once to reach a single digit.
98 9 + 8 = 17 -> 1 + 7 = 8
74 7+4 = 11 -> 1+1 = 2 59 5+9 = 14 -> 1+4=5
