So, might as well write something really silly we discussed. Take 360 degrees and dived it in two (or multiply by two. The numbers that come up add to 9.

- There are 360 degrees in a circle. 3+6+0 =9

- 180 degrees in half a circle. 1+8+0 =9

- 90 degrees is half that, 9+0 =9

- Half again = 45 degrees. 4+5 =9

- Alright now, halve that, 22.5 2+2+5 =9

- half again: 11.25. 1+1+2+5 =9

- once more: 5.625 5+6+2+5 =18. 1+8 =9

- Why is this?

Take any number. 12356 add eachvof the digits. 17. It is not divisible by 3 as a whole number so 123562 is not either. But 123561 is 18 so it is divisible by 3 as a whole number..

9x2= 18 9x9= 81 9×5= 45 9×6= 54

If this does not make math interesting I Don't know what will.
