Reassurance with my math
Finally found myself just playing around with my method for finding a modular inverse and was reassuring. Math is that way. Doing a post to let know am still active and to show it again.
So will calculate modular inverse of 19 mod 1001 which is 7(11)(13).
Let 2m = 1 mod 1001, then F0 = 19(19 + y0) mod 1001. Can pick y0 = 34. Then F0 = 6 mod 1001. That was lucky! Can pick whatever I like.
Picking so that F0 is as small as possible without 19 as a factor but coprime to 1001, and usually regardless have found need to recurse with coefficient of d as new modulus.
6d = (6n - 7)(53) mod 1001
6d = 318n - 371 mod 1001
And 6(167) = 1002 = 1 mod 1001 which is very convenient.
So: d = 53n - 896 mod 1001, so can use n = 1 and then d = -843. So 19-1 = 843 mod 1001.
Those values worked better than I expected, as of course really like easy. But yeah is very reassuring to just do some math and get the correct answer.
My way makes calculating the modular inverse so straightforward.
Am still active on this blog but often just reviewing. Have a lot of research results! Can play around endlessly with them.

Definitions drive innovation
Finally got around to defining mathematics and thought would emphasize how much a definition can help guide to new things never before considered.
Was back in 2005 when posted here my definition of mathematical proof which I discovered as got tired of screwing up so much.
Repeatedly my emotions got in the way and could take me MONTHS to find errors in mathematical arguments.
But with that definition could check even complex arguments in minutes.
Innovation has been at the forefront of what I do. And have over two decades now of discovery pushing past prior limits to ever greater knowledge. Better defining possibility is in definitions at the foundations.

Defining mathematics
Mathematics is a part of logic that is just about numbers and relationships between numbers.
Keys to analysis of numbers are conditional statements that are identities for a set of values for variables.
Identities are tautological statements with numbers. For example: 1 = 1
A conditional statement has variables for which is an identity.
For example: x2 + y2 = z2
Is a valid statement for x = 3, y = 4, and z = 5.
Then reduces to 25 = 25.
The sets of values for which a conditional statement is an identity are solution sets.
