multiply by 9, add the didgits?

[Jonathan-Joe]

Pick a number from 1 to 99. Form another number by reversing the digits. Subtract the smaller from the higher number. Add the digits in this difference. You will have answer "9".
Eg Pick 38. Reverse to form 83. 83 - 38 = 45. 4 + 5 = 0.

[Jonathan-Joe]

Typo - 4 + 5 = 9.

[bobbinwales]

think off a number . Like 8. Times it by 9. Thats 72. Add the didgits. Your answer will be 9
Try 12. 12 x 9= 108. Add the didgits 9.
Try 21. 21 x 9 = 189. Add didgits= 1+8+9= 18

[hansons]

what if you picked 22

[bobbinwales]

22 x 9= 198
1+9+8 =18

[bobbinwales]

Or try this.
think of a random number with 2 didgits. Example 34
Add the two digits (3+4=7).
Subtract the result from the first number you thought of (34-7=27).
Add the 2 didgits 2+7 =9

[bobbinwales]

think of 57.
5+7 =12
57-12= 45
add 4+5 =9

Think of 85
8+5= 13
85-13 =72
7+2=9

Something like that??
