You know what the funny thing is - I know I could just do some searching using the current mathematical tools easy and ask the question - what digit is most likely to end a prime number?

Or, better yet, I could take the computers they have nowadays and run the numbers up as high as they could go and then look at the data evident....of course there will be trends there as well....

and then - wa-la -

the code is broken once again but other codes remain and anybody understands a triangle or a 2-dimensional image, must realize there is endless code.....

still, in this season, can't deny - seems time for some code to be broken.

I got ideas on primes and hexagon shapes - I like to share...

you got a problem with that?

If so, it ain't my problem - tis yours!

This is what is on my mind…..

Well, here is the proof why any whole number ending in digit #9 is less likely to be prime versus whole numbers ending in digit #3 or digit #7 in base10. Assuming you have read the article, R U Ready?

1. 3*7=7*3=21. 3*9=9*3=27. 7*9=9*7=63. So, giving these each a “count of 1” versus counting them both ways, gives one ending in #1, one ending in #7, and one ending in #3, respectively.

2. The other possibilities are 3 * 3 = 9, 7*7 = 49, and 9*9=81. This gives 2 ending in #9 and one ending in #1.

3. Therefore, per the approach of not “double-counting” forwards and backwards, the totals are two ending in #1 and two ending in #9 versus just one ending in #7 and #3, respectively.

4. Therefore, whole numbers ending in #9 are less likely to be prime versus those ending in either #7 or #3, respectively.
