I'm adding value of the digits in a number, and I treat 0 as 1. I have not graphed this. I don't know a lot about math, but I seem to have a way of systematically obtaining a sequence from "normal" numbers. It goes like this: 35 = 2 34 = 1 33 = 0 32 = 1 31 = 2 30 = 2 29 = 7 28 = 6 27 = 5 26 = 4 25 = 3 24 = 2 23 = 1 22 = 0 21 = 1 20 = 1 19 = 8 18 = 7 17 = 6 16 = 5 15 = 4 14 = 3 13 = 2 12 = 1 11 = 0 10 = 0 9 = 9 8 = 8 7 = 7 6 = 6 5 = 5 4 = 4 3 = 3 2 = 2 1 = 1 0 = 1 1 = 1 2 = 2 3 = 3 4 = 4 5 = 5 6 = 6 7 = 7 8 = 8 9 = 9 10 = 2 11 = 2 12 = 3 13 = 4 14 = 5 15 = 6 16 = 7 17 = 8 18 = 9 19 = 2 20 = 3 21 = 3 22 = 4 23 = 5 24 = 6 25 = 7 26 = 8 27 = 9 28 = 2 29 = 2 30 = 4 31 = 4 32 = 5 33 = 6 34 = 7 35 = 8 Has anyone come up with this sequence before? If yes, is there a name of it, or has it been categorized?

Throw us a bone here. How is 35 > 2? Wouldn't the values of the digits 3 and 5 give 3 + 5 = 8? It looks like you are treating 35 to be (3)(5) but that isn't how you defined the process. OEIS doesn't have it. Dan Last edited by topsquark; July 19th, 2018 at 08:22 PM.

35, I look at it this way 3 and 5. 3 + 5 = 2, or to make it easier 5 + (3) = 2. Just adding the numbers that make up 35 and all other numbers that I listed.

Let me give some examples, so that you see better what I mean. Lets try number 10,000. I stated that I count 0 as 1, so 4x0 I count as 4x1 = 4 Then 1 + 4 = 3 Lets try another number, 2438. 2 + 4 + 3 + 8 = 17, and then adding 1 + 7 = 8 I guess, an application of this could be, taking a year 1984 for example. 1 + 9 + 8 + 4 = 22 so that is 2 + 2 = 4 Last edited by Alamar; July 20th, 2018 at 09:59 AM.

1234567890 = 1+2+3+4+5+6+7+8+9+0 = 45+1 = 46: 4+6 = 10 ????????
