The 9's complement of a digit is the number you need to add to it to make that sum equal to 9. Let's use the tilde symbol '~' to mean the 9's complement of.

Code:

~0 = 9

~1 = 8

~2 = 7

~3 = 6

~4 = 5

~5 = 4

~6 = 3

~7 = 2

~8 = 1

~9 = 0Well... after your explanation It sounds easy.

I never herd of it.

But binary doesn't go to 9 only 2 (0 and 1)

Would it be like...

0000 = 1001

0001= 1000

0010= 0111

...ect...
