I’m trying to find the perfect telephone number. What defines the perfect number and what is yours? Do you have it?
The perfect telephone number is one that includes all ten digits – you know 1-2-3-4-5-6-7-8-9-0. I’m not enough of a mathematician to know how to calculate them but let’s start by explaining that a mathematical formula similar to “8x9x7x6x5x4x3x2x1” will define them. I know this is not the correct total, so I hope someone can provide more information about the correct calculations.
Here’s what I remember from my college mathematics and why I know the above formula does not correctly define the total. The area code cannot begin with either 0 or 1 because they are reserved for the operator and 10 digit dialing. That leaves 8 digits as the first possible number, then there are 9 digits available for the 2nd place, 7 for the 3rd place, and so on. In addition, the first digit in the local number (which is the 2nd grouping of three) also cannot include a “0” or a “1”, but I’m not sure how you handle that. Anybody . . .?
The reason I’m asking is because I’ve found 3 almost perfect numbers – those with 9 digits. My number is 815-236-2904 (9 digits), Monkey and Dog Books is 817-975-4260 (9 digits), and Chapter2 Books is 651-239-4678 (9 digits).
The reason I came across this interesting issue is my continued attempt to market “Have You Seen My Daddy’s 18 Wheeler?” The American Booksellers Association lists more than 285 independent booksellers, with their telephone numbers. I’ve contacted many of them and discovered these two 9 digit telephone numbers.
I’ll tell you what I’ll do – If you can provide a “Perfect” telephone number, contact me at firstname.lastname@example.org and I will send you a free copy of “Have You Seen My Daddy’s 18 Wheeler?”.
