Rational numbers, also known as irrational numbers, are whole numbers (i.e., all positive numbers greater than zero) and their inverse (complementing numbers that are equal to zero), namely -infinity. Rationals, unlike irrational numbers, are always true. In other words, a rational number cannot be negative. Fractions are composite numbers, which consist of a prime number and an infinite number or sub-prime number.

An infinite number or sub-prime number, on the other hand, has a prime number as an infinite number followed by an infinite number or sub-prime number. Therefore, it is said that there are no primes lower than q(0) and there are no sub-primes higher than q(-) Therefore, what is a rational number is not the size of the number itself but the sum of the sizes of the primes, i.e., the size of the prime and the sub-prime. It follows that the size of the fraction should not be the size of the sub-prime because it can only be made larger by adding more prime numbers onto it.

One can define what is a rational number by taking the logarithm of its arithmetic mean and by taking its geometric mean. Logarithms, or the scientific measurements of measurement, are the mathematical equivalents of real numbers. For instance, a hundred is not really a hundred; it is just a mathematical calculation. Similarly, a thousand is not a thousand; it is also a geometric calculation.

If we take logarithms of smaller numbers to get sums of lesser numbers, then we get sums of even numbers, i.e., all even numbers less than 100 are not part of the logical or rational numbers. Hence, the question of what is a rational number becomes irrelevant. The sizes of the fraction may change, but the sums of all even numbers will always be even, because all even numbers have even numbers multiplied by themselves. Hence, if we take all even numbers equal to 100, the answer to the question what is a rational number becomes obvious.

Logical answers to what is a rational number become problematic because the irrational numbers, which appear on the real tables of measurement, do not yield to any imaginable mathematical calculation. For example, the square root of 15 is not a real number. It appears in the natural numbers, such as in birth tables and in geometrical and sphere coordinates. It is an impossible concept. Logical answers to what is a rational number become irrelevant because it is not possible to solve the equations associated with real numbers.

We can’t measure, say, the circumference of the earth or the diameter of the moon. But we can calculate the value of different rational numbers, like the square root of fifteen and the irrational numbers, e.g., infinity. Infinity appears as a transcendental object. It cannot be measured or calculated. Therefore, even if we could find a way to measure such irrationalities, what is a rational number would still remain elusive.

The easiest way to define a rational number is the one that sums to the nearest prime number, which is the arithmetic mean of the quotient of the first n numbers. We can call this the denominator. The denominator must be even if we make a mistake. It does not matter if the error is small or large; what is important is that the sum obtained is always even.

Similarly, the denominator can also be expressed as the highest power of any natural number, say the digits of the Fibonacci calculator. Let us say, for example, that the next digit to be added in the Fibonacci calculator will be six. Assume (as do most people) that we add nine instead. We get an answer of 9 squared plus the power of six, which equals the next digit. We can conclude that the rational number can be expressed as the largest positive prime number (such as the Fibonacci calculator) times the lowest power of that natural number (such as the digits of the calculator).
