The essence of the proof:
From the known properties of the Fermat’s equality An+Bn=Cn follows:
If the second digits of all the prime factors of the numbers A, B, and C are reduced to zero, then the new reduced numbers A°, B°, C° become /stay/ infinitely large.

Goldbach's Conjecture: “Every even integer greater than 2 can be expressed as the sum of two primes”.
In this document I used the prime numbers theorem enunciated by Carl Friedrich Gauss and the prime numbers theorem in arithmetic progressions. These two theorems applied to a combination of two arithmetic progressions of module 30 and that contain prime numbers, allows us to develop a nonprobability general formula to calculate, approximately, the number of prime pairs that adding up an even number x.
This research is based on a approach designed solely to demonstrate the Binary Goldbach Conjecture and the Twin Prime Conjecture.

I explore a method to characterize all the real numbers a,b such that all of $a - b, a^2 - b^2,...,a^n - b^n$ are integers for a given n and paying particular attention to the special case when neither of a and b are integers themselves.

Natural numbers have a strictly defined internal structure that is being revealed in the present article. This structure is inherent of the natural numbers and is not derived through the introduction of any axioms for the set of natural numbers. In the present article, we prove the fundamental theorems that determine this structure. As a consequence of this structure, a mathematical expression for the set of odd numbers that are not primes is derived. Given the set of odd numbers, we can identify the set of prime numbers. Additionally, a new method for expressing odd composite numbers as the product of powers of prime numbers is derived.

By convolving the distribution of one of the non-chosen runners with a step function (to introduce some uncertainty in its start time) we arrange that the mutual expectation reverts to the continuous extension of its value in the transcendental case.

The proof of Fermat's last theorem for the base case /
Доказательство ВТФ для базового случая
ABSTRACT
The essence of the proof:
From the known properties of the Fermat’s equality An+Bn=Cn follows:
If the second digits of all the prime factors of the numbers A, B, and C are reduced to zero, then the new reduced numbers A°, B°, C° become /remain/ infinitely large.
Суть доказательства:

In an earlier paper, “Q-Naturals: A Counter-Example to Tennenbaum’s Theorem,” we developed a set of non-standard naturals called q-naturals and demonstrated a counter-example to Tennenbaum’s Theorem. In this paper we extend the q-naturals to the Q-Universe and explore the properties of the various subsets along the way. In the process of this development, we realize that the standard Universe and the Q-Universe are simply the zeroth-order and first-order Universes, respectively, in a countable subsumption hierarchy of recursive Universes; there exist countably many counter-examples to Tennenbaum’s Theorem.

In this paper we propose a conjecture about prime numbers. Based on the result of Pierre Dusart stating that the n th prime number is smaller than n(ln n + ln ln n − 0.9484) for n ≥ 39017 we propose that the n th prime number is smaller than n(ln n + ln ln n − 1+) when n → +∞.

From the known properties of the Fermat’s equality A n +B n =C n follows:
If the second digits of all the prime factors of the numbers A, B, and C are reduced to zero,
then the new reduced numbers A°, B°, C° become infinitely large.
From which follows the truth of the FLT?

A positive integer is called Fixed Happy Cube Numbers (FHCN) in case, if you are cubing its digits and adding them together one time you got the same number. For example the number 153 is happy cube because;
153= 1^3+5^3+3^3, in fact this paper will address new propriety of this extraordinary happy cube number .

In this paper it is proved the existence of a prime number in the interval between the square of any natural number greater than one, and the number resulting from adding or subtracting this natural number to its square (Oppermann’s Conjecture). As corollaries of this proof, they are proved three classical prime number’s conjectures: Legendre’s, Brocard’s, and Andrica’s. It is also defined a new maximum interval between any natural number and the nearest prime number. Finally, it is stated as corollary the existence of infinite prime numbers equal to the square of a natural number, plus a natural number inferior to that natural number, and minus a natural number inferior to that natural number.

Division by 0 is not defined in mathematics. Mathematics suggests solutions by work around methods. However they give only approximate, not the actual or exact, results. Through this paper we propose methods to solve those problems. One characteristic of our solution methods is that they produce actual or exact results. They are also in conformity with, and supported by, physical or empirical facts. Other characteristic is their simplicity. We can do computations easily based on basic arithmetic or algebra or other computation methods we already familiar with.
