The uniqueness of the number nine

(Part 2)

Another fascinating properties of the number nine can be seen from the product of fruit number 12,345,679 with nine original numbers of the first nine multiples as follows:

12345679 x 9 = 111 111 111

12345679 x 18 = 222 222 222

12345679 x 27 = 333 333 333

12345679 x 36 = 444 444 444

12345679 x 45 = 555 555 555

12345679 x 54 = 666 666 666

12345679 x 63 = 777 777 777

12345679 x 72 = 888 888 888

12345679 x 81 = 999 999 999

Now try your own, on the other privileges of the number 9, by making the number 123 456 789 times with nine original numbers of the first multiple of nine. Is there anything interesting from the results of these times?

List the product number 987654321 with nine original numbers multiples of nine of the first looks like the following:

987654321 x 9 = 8888888889

987654321 x 18 = 17,777,777,778

987654321 x 27 = 26,666,666,667

987654321 x 36 = 35,555,555,556

987654321 x 45 = 44,444,444,445

987654321 x 54 = 53,333,333,334

987654321 x 63 = 62,222,222,223

987654321 x 72 = 71,111,111,112

987654321 x 81 = 80,000,000,001

Here are the results of the uniqueness of the number nine.

1 x 9 + 2 = 11

12 x 9 + 3 = 111

123 x 9 + 4 = 1111

1234 x 9 + 5 = 11 111

12345 x 9 + 6 = 111 111

123456 x 9 + 7 = 1111111

1234567 x 9 + 8 = 11,111,111

12345678 x 9 + 9 = 111 111 111

It also:

9 x 9 + 7 = 88

98 x 9 + 6 = 888

987 x 9 + 5 = 8888

9876 x 9 + 4 = 88 888

98765 x 9 + 3 = 888 888

987654 x 9 + 2 = 8888888

9876543 x 9 + 1 = 88,888,888

98765432 x 9 + 0 = 888 888 888
