SPECIAL NUMBERS

Among the necessary mathematical knowledge and skills in daily life, natural numbers, their properties and the relationships between these numbers, the operations performed with these numbers, the properties of the operations mentally skills have an important place.  Considering that mathematics education starts with counting and that I have numbers at every stage of mathematics education, exploration studies and projects can be made in this way for students in mathematics education.  Transferring number relationships to real situations is the basis for starting to make sense of the world in a mathematical way.  The world of mathematics offers a wide variety of number types, all of which have their own characteristics.  Mathematicians formulate theories about the relationships between numbers and number groups.  The most well-known special numbers among numbers are as follows,

  1. If there is a more interesting number than Pi, it is two Pi.  In other words, it is twice the 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.

2. This number, which we define as “e” in memory of the 18th-century mathematician Leonhard Euler, is the most known number after probable Pi.  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

3 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.

In 1979, French mathematician Roger Apéry proved that a value known as the Apéry constant is an irrational number.  (It starts with 1.2020569 and continues indefinitely.) The constant is also written as zeta (3);  this means placing the number 3 in the Riemann zeta function.  The Apéry constant appears in many places in physics, including equations that direct the electron’s magnetic strength and direction to its angular momentum

4 The numbers obtained by squaring a d number with N digits and adding the n-digit number on the right side and the number of n or n-1 digits on the left side of the number formed are called “Kaprekar Numbers”.  Kaprekar numbers are numbers described by the Indian mathematician Kaprekar in 1949.  For example;  The number 55

6. The number pi (π) is the irrational mathematical constant obtained by dividing a circle’s circumference by its diameter.  It gets its name from the first letter of the Greek word περίμετρον (circumference).  Also known as Pi number, Archimedes constant and Ludolph number.

We, as the 1st team, shared these special issues with 25 students from five different schools and my mentor teachers in our cad math e twinning project, in our online workshop activity, we shared our knowledge and created posters, some of them were shared.  While our students and we were researching these numbers, we asked the question where they come across in daily life  The increase of students’ interest in mathematics by discovering their special numbers and systems enabled them to develop their studies and creativity by loving mathematics more.
