I read an amazing article about the many patterns of 3's. And it included these patterns you get when you double up on any number divisible by 3: 3 x 2 = 6 = 6 6 x 2 = 12 ( 1 + 2 ) = 3 12 x 2 = 24 ( 2 + 4 ) = 6 24 x 2 = 48 ( 4 + 8 = 12 ( 1 + 2 ) = 3 48 x 2 = 96 ( 9 + 6 = 15 ( 1 + 5 ) = 6 96 x 2 = 192 ( 1 + 9 + 2 = 12... ) = 3 9 x 2 = 18 ( 1 + 8 ) = 9 18 x 2 = 36 ( 3 + 6 ) = 9 36 x 2 = 72 ( 7 + 2 ) = 9 72 x 2 = 144 ( 1 + 4 + 4 ) = 9 144 x 2 = 288 ( 2 + 8 + 8 = 18..) = 9 288 x 2 = 576 ( 5 + 7 + 6 = 18..) = 9 Try doing that with 1,2,4,5,7 or 8  Their condensed totals end up all over the place. Pretty cool huh |

As an accountant, we know when we are out if balance, the first thing you do is divide the out of balance amount by 9.
If the number is evenly divisible by 9, then normally that means someone transposed a number.
Example: someone wrote the number 108 they meant to write 180. We have a listing with lots of numbers with a total. We only know our total is out by $ 72, which is evenly divisible by 9 so we know that in our list of numbers, to look for a transposition error. Works every time.

Yep, we used a lot of tricks like that in "number sense" which were timed math competitions where you could only write down an answer in the blank. All calculations must be done in your head.
Honestly that's why I love math...so many cool patterns!

Honestly that's why I love math...so many cool patterns! I used to coach number sense. I love those mental math tricks. My kids always did awesome at completion. I've been trying to drill the divisibility rule for 3 and 9 all year with my 6th graders. Some how divisibility fell through the gap with this group. |

I read that when you bisect a circle you will always come out with 9 when you do the root. In Astrology I do this a lot because some of the main angles used for aspects are 180,90 ( and 45 is a minor aspect ) Which all root to 9 Also any number multiplied by 3 also roots to a 3,6 or 9 in that order. And the different Solfreggio frequencies all root to 3,6 or 9 in that order too. |
