Equation #2 is divisible by 9 or can be reduced to 9 when we subtract the number ... with this formula (N - Mirror(N)) % 9 == 0
We have found that all numbers are divisible or will reduce to 9 when you apply our formula of UNINE9METRY
00 to 00 gives 0
01 to 10 gives 9
02 to 20 gives 18
03 to 30 gives 27
04 to 40 gives 36
05 to 50 gives 45
06 to 60 gives 54
07 to 70 gives 63
08 to 80 gives 72
09 to 90 gives 81
10 to 01 gives 9
11 to 11 gives 0
12 to 21 gives 9
13 to 31 gives 18
14 to 41 gives 27
15 to 51 gives 36
16 to 61 gives 45
17 to 71 gives 54
18 to 81 gives 63
19 to 91 gives 72
20 to 02 gives 18
21 to 12 gives 9
22 to 22 gives 0
This adds another lather to the divisibility rule by showing that all numbers are divisible by 9

If you add the digits together for the answers of #1, #3 and #4, the sums equal 9. So, 18, 36 and 36 are 1+8 and 3+6 respectively. Can this fact be used as a tool to check that you have applied the divisibility rule correctly?

thanks so much this helped me and my sister l lot
