- One of the important number groups that we encounter in exams is the numbers we call Tau numbers. In this article, we will look for answers to questions such as what is the tau number and how to tell if a number is a tau number.
If a number is divisible by the number of positive divisors, that number is classified as a tau number. For example, the number 12 has 6 positive divisors, 1, 2, 3, 4, 6, 12. 12 is a tau number because it can be divided by 6.
How is the Tau number calculated?
First, the positive divisor number is found. We can do this by factoring. For example, the number 24 could be written as 2 3 .3 1 . Then we increase and multiply the tops by one to find the number of positive divisors. 2 and 4 are multiplied for 1 and 3. 2.4 = 8.
If the number is divided by the number of positive divisors, we say this number is the number of tau. 24 is a tau number since it is divided by 8.

The sequence of Belphegor Primes is the same from left to right and right to left, so it is a palindromic prime number. In addition, there are 666 in the middle and 13 0s on each side
of it. This number was named after Belphegor, one of the seven princes of hell, due to the bad luck attributed to the numbers 666 and 13 in Western cultures. It is itself a palindromic prime number because the sequence of its digits is the same from left to right and from right to left. In addition, there are 666 in the middle and 13 0s on each side of it. This number was named after Belphegor, one of the seven princes of hell, due to the bad luck attributed to the numbers

2 . If there is a more interesting number than Pi, it is two Pi. In other words, it is twice of Pi. This number, known as the Tau number , has a value of approximately 6.28. While pi relates the circumference of a circle to its diameter, tau relates the circumference of a circle to its radius,
and many mathematicians argue that this relationship is much more important.
However, Pi has become so embedded in mathematics that it is extremely difficult to extract. It would be a more practical approach to teach the two together instead of using Tau for Pi.
PI number; is a mathematical constant expressing the ratio of the circumference of a circle to the diameter of that circle . It is denoted by π , the first letter of the Greek word περίμετρον, meaning environment . Pi number is an irrational number. The decimal does not end
as an integer (= 0.25) or repeat infinitely (1.66666…). It is also called the Archimedes
constant or the Ludolph number. Trillions of digits pi is actually “what is”?
Divide the circumference of a circle by the diameter of the same circle, regardless of its
size, and you get approximately 3.14. This is the number pi. We say approximately
because the number pi has quite a few digits. Finally, 31.4 trillion digits were calculated by Google employee Emma Haruka Iwao in 2019. Iwao holds the record for now.
Draw a circle using a compass to get the correct size. Take a rope and wrap it around the circle. Open the rope and measure its length. Find the diameter of the circle you created by measuring the distance from any point of the circle to its opposite point from the center. Note that the circle diameter is twice the radius. Divide the circumference of this circle you have obtained by the diameter of the circle. Regardless of the width of the circle, if you proportion the value you get , it will be approximately 3.14. You can get all the way up to the trillionth digits of pi by trying the measurement indefinitely. This magic mathematical constant has been used for
thousands of years.

3. 6174 is known as Kaprekar’s constant[1][2][3] after the Indian mathematician D. R. Kaprekar. This number is notable for the following rule: Take any four-digit number, using at least two different digits (leading zeros are allowed). Arrange the digits in descending and then in ascending order to get two four-digit numbers, adding leading zeros if
necessary. Subtract the smaller number from the bigger number. Go back to step 2 and repeat.
The above process, known as Kaprekar’s routine, will always reach its fixed point, 6174, in at most 8 iterations.[4] Once 6174 is reached, the process will continue yielding 7641 –
1467 = 6174. For example, choose 1495:
9541 – 1459 = 8082
8820 – 0288 = 8532
8532 – 2358 = 6174
7641 – 1467 = 6174
The only four-digit numbers for which Kaprekar’s routine does not reach 6174 are repdigits such as 1111, which give the result 0000 after a single iteration. All other four-digit numbers
eventually reach 6174 if leading zeros are used to keep the number of digits at 4.
3. i number above i
If you find the number i strange, consider the number i over i. To calculate the
value of i for i, we need to use Euler’s formula and rearrange it. When solving
the formula for a 90 degree angle, the i top i is roughly equal to 0.207, which is a
very real number. If you want to examine the solution in detail:
https://divisbyzero.com/ But let’s remind you. i above i do not have a single value.
It can take an infinite number of values depending on the angle chosen.
5. An Imaginary Number: i
Although we are told that a negative number cannot have a square root, the number i turned out to be a rule breaker. The definition of the number i is that its square is -1. With the definition of the number i, mathematics got rid of the real number line where it was stuck and switched to the two-dimensional number line.

6. e number
This number, which we define as “e” in memory of the 18th century mathematician Leonhard Euler, is the most known number after the probable Pi. This number, whose infinite value is accepted as 2.718281 with the first six of the decimal places, is the “Euler number” , named after the mathematician who introduced him . also known as. This number is frequently encountered in determining population growth, when we are dealing with financial
mathematics, and in probability and statistical calculations. The number of e plays a key role in matters related to growth. For example, economic growth and population growth are among them. Radioactive decay models are also based on the number e. But among all
these growth relations, the most interesting thing is, of course, interest calculations.
