Forty-five years ago a man in Mexico showed me how he created a five digit number from the date of a coin to help him choose a lottery number. It goes like this:
1957 is the number. Add the digits individually: 1 + 9 + 5 + 7 = 22
Add the two digits of the sum 2 + 2 = 4; I'll call that reduction the "final sum."
So he looked for the lottery ticket 19574. That's numerology.
Playing with it in my head (it can be a number of any length of digits), I found that the sum of any recombination or transposition of the digits results in the same "final sum" of 4.
19 + 57 = 76 7 + 6 = 13 1 + 3 = 4
1 + 957 = 958 9 + 5 + 8 = 22 2 + 2 = 4
195 + 7 = 202 2 + 0 + 2 = 4
transposing the numbers to give more examples:
95 + 17 = 112 1 + 1 + 2 = 4
97 + 15 = 112 1 + 1 = 2 = 4
175 + 9 = 184 1 + 8 + 4 = 13 1 + 3 = 4
71 + 95 = 166 1 + 6 + 6 + 13 1 + 3 = 4
et cetera et cetera
I understand the commutative law of addition, but that does not explain it completely. I have not found a number of any (reasonable to work with on paper or in my head) length in which no matter how you recombine or transpose, the "final sum" is the same single digit number.
What is this called? Is it documented by someone somewhere? Does the explanation belong to a subset of Mathematics?
I eagerly await the inspection by authorities. I hope that I can understand an explanation that may be more complex than I expect.
Other than this, I am not equipped to contribute much to this website except to thank you for your interest or laugh at my naiveté.
Mil gracias,
