What can you do with the number 9?

[RemyZee]

I am not a fan of numbers in that I have dyscalculia and they are swirling blobs to me, although I truly like the IDEA of numbers. But I've just learned there are all kinds of unusual, unexpected, absorbing things a person can do with the number 9, and it's given me an appreciation of the mysteries of numbers--though the calculations are difficult for me to understand because my noggin stops working and starts rebelling around the count of 15. I thought I would put this thread up to ask, for whoever is into numerals: what are some weird and whacky things you can do with 9?.

Add 9 to 9 and you get 18 add 1 and 8 and you get 9
add 9 to 18 and you get 27 add 2 and 7 and you get 9
add 9 to 27 and you get 36 add 3 and 6 and you get 9
this pattern continues all the way to 81

Add 9 to 9 and you get 18 add 1 and 8 and you get 9
add 9 to 18 and you get 27 add 2 and 7 and you get 9
add 9 to 27 and you get 36 add 3 and 6 and you get 9
this pattern continues all the way to 81

It goes beyond 81.
9+0
9+9 =18, that's a break in the pattern, then:
1+0+8
1+1+7
1+2+6
Etc.

Add 9 to 9 and you get 18 add 1 and 8 and you get 9
add 9 to 18 and you get 27 add 2 and 7 and you get 9
add 9 to 27 and you get 36 add 3 and 6 and you get 9
this pattern continues all the way to 81

If, when you get to 90 (=81+9) and add 9 to get 99, add 9 and 9 to get 18, then add 1 and 8, you get 9. So if you always recursively sum the digits until you get a single digit, it is always 9, i.e. the series is infinite.

You can eat it!

Like how 7 8 9 (seven ate nine).

Put 6 and 9 together and you have an enjoyable evening ahead of you.

Take any integer and distill it down as above,
Example: 2026,
2 + 0 + 2 + 6 = 10;
1 + 0 = 1

When you divide 2026 by 9, its remainder will also be 1 !

(The only exception is if it distills down to 9, the remainder will be 0.)

Nine is the first square of a number larger than two.
It is the largest single-digit number.
When you see a line of them on an odometer, you can soon see a rare sight.
In numerology it sums up your life, or something like that.
On a sign using vinyl letters, if there is a typo interchanging a six with a nine, the installer can fix it. (happened to me, startling hell out of my boss, who had just switched from paint)
If there are too many of them in a column of expenses, it gets flagged as more likely to be fraud than random.
Retailers like nines in the cents column to reduce sales resistance.
This is my ninth entry.

Retailers like nines in the cents column to reduce sales resistance.

Originally, nines in the cents column forced staff to ring up sales on the cash register to make change, reducing staff pilfering.

Revolution #9.

If you play it backwards, it says "Turn me on, dead man."

Every time I hear the phrase "number nine" I automatically hear "turns me on, dead man."

Unless you but them in the wrong order. If you do that, it's just stupid.
