I am one of the luckiest people in the world. I know because I got to study mathematics, well statistics and economics mostly, but still a branch of mathematics. It was certainly one of the most interesting challenges/experiences ever in my life. There is a beauty [in designing equations] in modeling real-life problems and solving them, even the proving out of solutions, not in a workshop but on paper, or a chalkboard. Truly amazing how once you’ve properly identified pertinent variables and manipulated their components under mathematical rules and arrived at a solution uncovering the correlation that exists between certain properties, or variables, that’s fascinating! The [mathematical] beauty of something proving itself out on paper can keep one coming back for more, kind of like making that one great shot in a golf round.
I bounced around forever back when I attended college courses and probably changed my major at least four times before I finally settled on majoring in Quantitative Methods (Statistics) then Economics. Math was one of the few courses I didn’t struggle much in during grade school, and Economics I remember interested me even back in 7th to 8th grade. Looking back on my scholastic record it looked mostly like a bowl of spaghetti early on, nothing made much sense. I couldn’t see any direction, it wasn’t until years later that choosing a track of Statistics and Economics began to pay off because I could finally see things clearly, partitioning them into categories and reasons I could interpret, understand and allowing me to design courses of action of benefit to me and the people I would advise. For that I’m grateful to God as I certainly didn’t plan this, I didn’t even see where this [bowl of spaghetti] was going until many years later.
So let’s discuss the mysterious Number 9. This number fascinates me since I found out on my own that when adding a numerical sequence with the sole purpose of reducing additions to a single digit the number 9 does some very interesting stuff that no other number does… before I present simple examples to my case I recently saw a piece someone else wrote on the number 9 having some unique properties. 9 is the only number that when multiplied by any other number, (except for 0 because anything multiplied by zero = zero), that the sum of the remaining digits will always equal 9. This concept is somewhat related to my personal discovery about the number 9 as well. So let’s look at what he was talking about with the number 9 first:
Examples:
1 x 9 = 9
2 x 9 = 18, and 1+8 = 9
3 x 9 = 27, and 2 +7 = 9,
… and so on, therefore 10 x 9 = 90, and 9 + 0 = 9.
So any and all multiplications of 9 will end up summing to a single digit of 9 as well. This is the only known number with these qualities.
Here’s what I discovered about the number 9. First as an example, I’m going to punch in a long sequence of numbers randomly, presented below –
15673980348592670573
Next, let’s remove all 9’s from this number sequence above PLUS I’m even going to remove all combinations of numbers from the above sequence that I find that even add up to 9! [but no worries if we miss one or two].
Here’s what I have left from the above sequence of numbers after this operation:
5703860573
Okay, I have reduced the number, but wait! I see there’s still two numbers that can add up to 9, so let’s remove the only 6 left in the sequence and just one of the 3’s:
Okay, now we have reduced my original number sequence down to just 57080573.
At this point all 9’s and sums of any two numbers that would have equaled 9 have been deleted from the original sequence, and now we’re going to simply add up the remaining numbers to reduce this long number string to one single digit:
5 + 7 + 0 + 8 + 0 + 5 + 7 + 3 = 35, and 3 + 5 = 8.
So the summation of my final string of numbers can be reduced to the number 8.
Okay, now we’re going to go back to my original number string, it’s quite long, and we’re going to add up every one of those original digits just to compare the two answers, and see whether my number 9 theory will prove out correct:
Remember my original number sequence above was 15673980348592670573.
So, 1 + 5 + 6 + 7 + 3 + 9 + 8 + 0 + 3 + 4 + 8 + 5 + 9 + 2 + 6 + 7 + 0 + 5 + 7 +3 = 98, and 9 + 8 = 17, and 1 + 7 = 8.
Wha-la! Same result as above where I eliminated all 9’s and even any two numbers that would add up to 9 from the original long number string. Truly amazing stuff this number 9 is!
Now the question remains, can any real-life applications be found for the uniqueness of number 9? Usually mathematical discoveries do find applications but only many years after the fact. Isaac Newton invented Calculus and many of us have been challenged with a course or two, or even three of those. It’s many applications include the measuring of velocity… I’m just doing my small part here, making you geeks aware that there’s something going on with the Number 9. 🙂

I was hanging at the G7 and headed to Germany to visit a city of the future with no carbon emissions, they’re curious why nothing works on cloudy, windless days but they’re working on it. The city’s name is Ferk Jer Berden. I ran into Joe Biden and he wanted to personally wish you a Happy Fourth of Easter!
Hahahahaa-ha!I took an inventory of things sitting on my desk, just to see if I could find something – just one thing that I could claim is “carbon-free”, or at least manufactured by a carbon-free process:
One side table lamp with metal lampstand and kind of indian style lampshade made out of leather
One No. 2 pencil with carbon filled led
A stack of at least 8 white personal notepads from back when I was actually working, they have my name rank and serial number on them from ML
A framed picture of “Bossy Boy” my favorite dog
A rolodex card file with clear plastic top
A leather card holder with my old business cards inside
One used tube of Aquaphor lip balm for chapped lips from talking too much [I should really work on that]
One small plastic bottle of Zeiss Lense cleaner
A stapler made of black plastic loaded with staples
A framed photo of of middle school Blaise practicing his cello in our old formal living room on a Christmas Day
One i-phone charger cord
A red, white, and blue ribbon bow used to bind a copy of The Declaration of Independence I bought while on a visit to Philadelphia, where it was signed
My favorite wooden back scratcher, made by slave labor somewhere in an Asian jungle
One opened bag of Dark Chocolate Rolos
One Amazon firestick TV remote made of plastic
A copy of the Tony Evans Bible Commentary book
A small box of Kleenex
A coffee cup that was given to me by a wholesaler for Van Eck Funds, it contains writing pens, a staple remover, and a pair of scissors
One Lenovo laptop made of plastic and metal parts, the brainchild behind my brantology blog
One piece of large clear glass that covers and protects half the surface of the desk from scratches and gouge marks
Sitting under the glass is that copy of the Declaration of Independence purchased in Philly, plus the led pencil scorecard from a recent golf outing where I shot a 91 and my buddy just barely beat me by shooting a 90.
And finally, in the corner of the desk, hidden behind everything else is old plastic bottle of Kroger hand sanitizer, says on the bottle it’s waterless and flammable
Not one of these items doesn’t have a carbon footprint. I LMAO @ Liberal Woke Leftist Progressives daily around here!
And all this time I was thinking, it’s got to be in the same hood as 10 Downing or just the end of a Beatles song.
Factoid: Most of us remember the eminent death and destruction of planet earth that was to take place on Jan 1, 2000. The true date was 9999; why? So much code ended in 999. Beta testing was nearly complete in 98. 1001 had been forgotten as well as 100 = 4. Thank you Mr Barton!
Of course, the world was going to end because computers were not programmed for the year 2000. Software upgrades went viral and software companies sold a ton more than they would have back then. Software stock paybacks were a bitch… everyone knows where tech stocks went after January 1, 2000.
Nice! This is called the “digital root.” Numberphile did an episode on this exact phenomenon. https://m.youtube.com/watch?v=FlndIiQa20o
In the strange case where a number sequence contains only numbers that can be summed up to 9’s, like this one –
1854637218. Where pairing 1 + 8 and 5 + 4 and 6 + 3 and 7 + 2 and 1 + 8 = 9 + 9 + 9 + 9 = 45 wherein 4 + 5 = 9 final answer. You cannot eliminate every number to arrive at an answer otherwise the above number sequence would have equaled zero. In cases like this you must respect that the answer to their summation is simply 9.
Let’s add another digit onto the end of the above sequence to make it 18546372185. In this case because all numbers in the sequence can be combined into 9’s with the exception of the last digit “5”. The answer to the summation of this number sequence is simply 5. To prove this is easy –
1 + 8 + 5 + 4 + 6 + 3 + 7 + 2 + 1 + 8 + 5 = 50, and 5 + 0 = 5. 🙂
