no, you cann add 2 or 3 etc... and get some result, this is not so easy...
Exactly, each additional amount you increment the term by makes even more point additions hence makes the result look more "pseudorandom".
Topic: SECP256k1. Why this happen? (Read 223 times)
Exactly, each additional amount you increment the term by makes even more point additions hence makes the result look more "pseudorandom".
You're getting such a wild difference because every time you add 1 to a factor, you are performing another point addition, the operations of which are non-trivial and are described here. It allows several opportunities for the result to overflow which triggers a modulus, hence why you also can't see a relationship between the two results at a first glance.
I hope I will understand difference betwin factors and not factors and not a factors.

Glad to help you 
i used floor division to obtain that number (python language) NR_A // NR_B
0xc65a01ff0c01162e7d2af2fc9ff9caf699c3cc9cfecc0353fe8b4853449c555a7e8c0b7cbbc50 79 // N = 0xc65a01ff0c01162

Thank You Very Mach Minase !!! Now I uderstand mach more.
and I was send you 1 merit.

you mean this number ? 0xc65a01ff0c01162 ? how i calculated this?
yes Bro
How ?
you mean this number ? 0xc65a01ff0c01162 ? how i calculated this?
% is the modulus operator.
Almost any programming language have it implemented. simple % or double %% (depending on the language)
LARGE_NR % N = remainder
Almost any programming language have it implemented. simple % or double %% (depending on the language)
LARGE_NR % N = remainder
But you compute exact reminder, how you do it ?
How you get 0x65a01ff0c01162 bro ?

@Minase, bro,how to compute reminders ?
because at the first result 0xfc07a1825367bbe you add 0xE7D2AF2FC9FF9CAF795D2EED256567679873FC547A513AA85A8A2E2776AB88D9 and you obtain 0xe7d2af2fc9ff9caf795d2eed256567679873fc547a513aa86a4aa83f9be20497
0xe7d2af2fc9ff9caf795d2eed256567679873fc547a513aa86a4aa83f9be20497 * 1 = 0xe7d2af2fc9ff9caf795d2eed256567679873fc547a513aa86a4aa83f9be20497

Bro, yo talk about not first rsult, you talk about second result
first result is a db09b0615ad40a0
this - 0xe7d2af2fc9ff9caf795d2eed256567679873fc547a513aa86a4aa83f9be20497 second result.
Thank you, I understand now were from "many" numbers was come.

then to 0xdb09b0615ad40a1 result = 0xe7d2af2fc9ff9caf795d2eed256567679873fc547a513aa86a4aa83f9be20497

What is this for "magic" number ? This is not mod(n) not prime or what
?
p.s. all numbers were is a private keys.
