Kokonaisien

Kokonaisien is a Finnish word that translates to "integers" in English. In mathematics, an integer is a whole number that can be positive, negative, or zero. Integers are a fundamental concept in number theory and are used extensively in various branches of mathematics and computer science. They are denoted by the symbol Z, which stands for the German word "Zahlen," meaning numbers.

The set of integers is infinite and can be represented on a number line, with positive integers to the right of zero and negative integers to the left. The set of integers is closed under addition, subtraction, and multiplication, meaning that the result of these operations on any two integers is always another integer. However, division of integers is not always an integer, as it can result in a fraction or a non-integer value.

Integers are used in various mathematical concepts, such as divisibility, prime numbers, and modular arithmetic. They also play a crucial role in computer science, where they are used to represent discrete values and perform calculations. Understanding integers is essential for grasping more advanced mathematical concepts and solving real-world problems.
