No matter what 2 digit number you pick, you end up with a number divisible by 9 after you subtract the digits. And if you look at all of the numbers divisible by 9 on their chart, they all have the same object. Their chart changes every time you do it, so the divisible by 9 fields might be bunny slippers one time and cat figurine the next time.; ▶ Reply to This

The year I was born 1952 1+9+5+2 = 17
1+7 = 8
Now add the numbers without the 9:
152 1+5+2 = 8
The 9 might as well not be there.
This is just one trick I know about 9, from numerology stuff. There's a ton more.; ▶ Reply to This

If you transpose 36 to 63, your difference is 27, which is divisible by 9. So if your total is off by a multiple of 9, it means that you've probably transposed a number somewhere. I use this one every day.; ▶ Reply to This
