# SAYI KÜMELERİNDE İŞLEMLER

Sayı Kümeleri

Rakam = {0,1,2,3,4,5,6,7,8,9}

Sayma Sayıları = {1,2,3,...}

Doğal Sayılar (N)={0,1,2,3,...}

✔

Sayı Kümelerinin Hiyerarşisi

Matematikte sayılar belirli kümeler halinde organize edilir ve her küme bir öncekini kapsar. Rakamlar sadece 0'dan 9'a kadar olan tek haneli sayılardır - bunlar sayıların yapı taşlarıdır.

Sayma sayıları {1,2,3,...} günlük hayatta nesneleri saymak için kullandığımız sayılardır. Doğal sayılar ise sayma sayılarına 0'ı da ekleyerek oluşur: {0,1,2,3,...}.

Tam sayılar doğal sayıları negatif yönde genişletir: {...,-2,-1,0,1,2,...}. Tam sayılar kendi içinde üç gruba ayrılır: negatif tam sayılar, sıfır ve pozitif tam sayılar.

Dikkat: Her sayma sayısı aynı zamanda doğal sayıdır, her doğal sayı da tam sayıdır. Bu hiyerarşik yapıyı anlamak çok önemli!

Rasyonel sayılar m/n şeklinde (m ve n tam sayı, n≠0) yazılabilen sayılardır. Yani kesirler, ondalık sayılar bu gruba girer. İrrasyonel sayılar ise hiçbir şekilde kesir olarak yazılamayanlar - π, √2 gibi. Gerçek sayılar tüm rasyonel ve irrasyonel sayıların birleşimidir.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
