I’ve always been partial to the number 8. After all, I was born on the 8 th day of the 8 th month in a year, which if you add up all four digits, the result is 8. Eight turned on its side is the symbol for infinity, which is cool. And the number 8 stands for abundance. But I’ve always found the number 9 to be magical.

The simple arithmetic tricks that you did to amaze your friends in grade school (guessing which card they chose from a small fixed set or guessing what number they chose, etc) were all based on the use of the number 9 and the principle of casting out nines to check sums, quotients and products. Because our counting system is based on ten, nine as the last number before the place Air Jordan Spizike holder zero, has some special properties.

Nine times any other number will result in nine, ultimately. Take the simple case of 9 x 2. It equals 18. When you perform 1 + 8, you get nine. Taking a less simple case, perform 9 x 327 and you get 2,943. 2 + 9 + 4 +3 = 18, and 1 + 8 = 9. Voila!

Nine plus a single digit number will result in Jordan Retro 8 the number you added to nine, again ultimately. 9 + 2 = 11 and 1 + 1 = 2. 9 + 3 = 12 and 1 + 2 = 3.

Nine plus a double digit number will yield the same result as if you added the two digits of the double digit number you added to nine. Well, look at it this way: 9 + 13 = 22; both 13 (1 + 3) and 22 (2 + 2) add up to the number four; also 9 + 41 = 50 (4 + 1 = 5 and 5 + 0 = 5).

Nine, plus or minus a double digit number gets interesting. Consider 9 + 33 = 42. The four and two add up to six. Now consider 33 9 = 24. Not only do the two and four add up to six, 24 is the opposite of 42, although that is not always the case. Another example is 9 + 29 = 38. 3 + 8 = 11 and 1 + 1 = 2. Then take 29 and subtract 9 to get 20, and the 2 and 0 add up to 2. And there is another relationship here, do you see it?

Any number that is evenly divisible by nine will ultimately add up to nine. For example: 18 9 = 2. Two is a whole number and the 1 and 8 of 18 add up to 9. Also consider 351 9 = 39. Thirty nine is a whole number and 3 + 5 + 1 = 9.

Here’s a neat trick (well probably only neat to a nerd): If someone asks you if a particular number is evenly divisible by nine, just quickly add together all the digits. If the ultimate result is not 9, then it is not evenly divisible Air Jordan Fusion 5 by 9. Is 1,027 divisible by 9? No, but 1,026 is.

Here are some interesting facts about the number 9:

The number 9 is revered in Hinduism and considered a complete, perfected and divine number because it represents the end of a cycle in the decima l system, which originated from the Indian subcontinent as early as 3000 BC.

Important Buddhist rituals usually involve nine monks.

The first nine days of the Hebrew month of Av are collectively known as “The Nine Days” ( Tisha HaYamim), and are a period of semi mourning leading up to Tisha B’Av , the ninth day of Av on which both Temples in Jerusalem were destroyed.

Nine, as the highest single digit number (in base ten ), symbolizes completeness in the Bah’Faith. In addition, the word Bah’ in the Abjad notation has a value of 9, and a 9 pointed star is used to symbolize the religion.

Nine is a significant number in Norse Mythology . Odin hung himself on an ash tree for nine days to learn the runes.

The Fourth Way Enneagram is one system of knowledge which shows the correspondence between the 9 integers and the circle.

In the Christian angelic hierarchy there are 9 choirs of angels.

Anton LaVey applied the number to Satan .

Ramadan , the month of fasting and prayer, is Nike LeBron 11 the ninth month of the Islamic calendar .

Casting out nines is a quick way of testing the calculations of sums, differences, products, and quotients of integers, known as long ago as the 12th Century.

I’ve always been fascinated by numbers, but not so much so that I wanted to become a mathematician. I have no head for math. It took me two tries to get through algebra. I would never have passed geometry without the help of the man who eventually became my husband. Trigonometry was a mystery and I remember nothing whatsoever of calculus except for the relief I felt when I passed the course. But I love numbers all the same.

Here’s another interesting fact concerning the number 11. You can quickly and easily (well relatively easily, depends on how good you are at visualizing what you are thinking about) multiply 11 times anything by a simple trick and some addition.

Take for example, 11 x 13. In your mind’s eye, take the 1 and 3 of 13 and separate them. Then add the 1 and 3 together to get 4 and place it between the separated 1 and 3 to get 143. Check it out on a calculator, it’s cool. Here’s another one: 11 x 49. Separate the 4 and 9, perform 4 + 9 to get 13 aha you say the result shouldn’t be a four digit number and you are right. Because 4 + 9 results in a two digit number, you must carry the one over to the 4 to result in 5, put the 3 in the middle and leave the 9 on the end for 539. When you start multiplying 11 times three digit numbers, you have to be really good at the visualization thing. But it works every time. Believe me. I’ve tested it out. Don’t ever believe me, though, if I try to tell you that I am not anal and have no obsessive/compulsive tendencies whatsoever. And Air Jordan 13s what do you do in the middle of the night when you can’t sleep? I was eight years old when I discovered the magic of nine one sleepless night. And I can tell you that I am not turning my shoes inside out in my mind and trying to determine which foot they will now fit right or left? I grew out of that one at about age you guessed it 9.
