Egészértékek, also known as integers, are a fundamental concept in mathematics. They are the set of numbers that include all the natural numbers (1, 2, 3, ...), their additive inverses (-1, -2, -3, ...), and zero (0). The set of integers is typically denoted by the symbol Z, which stands for the German word "Zahlen," meaning numbers.

Integers are distinct from other types of numbers, such as rational numbers, which include fractions and decimals, and irrational numbers, which cannot be expressed as a simple fraction. Integers are closed under addition, subtraction, and multiplication, meaning that the result of these operations on any two integers will always be another integer.

The properties of integers are crucial in various branches of mathematics, including number theory, algebra, and calculus. They form the basis for many mathematical concepts and are used extensively in problem-solving and real-world applications. Understanding the properties and operations of integers is essential for anyone studying or working in fields that involve mathematics.
