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...
It is 90
It is five.
To find the 9s complement, subtract each digit from 9: 27 → 72
The GCF of 9s and 63s^3 is 9s.
You could have one No. 9 or a handful of No. 9s
9s + 7 = -11 9s = -18 s = -18/9 s = -2
The GCF is 9s.
Five 9s:(99 x 9 + 9) / 9 = 100
Since 9s is a factor of 36s, it is automatically the GCF.
The equivalent is 7s+2s = 9s
You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6
The next year after 1999 that will have three 9s in its title will be 2999.
