Heltalene
Heltalene refers to the set of integers, encompassing all whole numbers, both positive and negative, along with zero. This mathematical concept is fundamental in number theory and algebra. Integers are denoted by the symbol ℤ, derived from the German word "Zahlen," meaning numbers. Each integer is a unique element that can be expressed as an n or –n, where n is a natural number, except for zero.
The properties of the integers include closure under addition, subtraction, and multiplication, meaning the result of
Integers can be represented in various numeral systems, most commonly decimal and binary. In binary, every integer
Applications of integers span numerous fields. In algebra, integers form the basis of polynomial arithmetic and
