Reaalnumbrimaailmas
Reaalnumbrimaailmas is a term used to describe the world of real numbers in mathematics. It denotes the system of real numbers, equipped with the usual addition and multiplication and the standard order, forming a complete ordered field. The real numbers encompass both rational numbers (fractions) and irrational numbers (numbers that cannot be expressed as a simple fraction).
The real numbers can be constructed in several equivalent ways, such as through Dedekind cuts or via
In relation to other number systems, the real numbers constitute a subfield of the complex numbers, and
Applications of the real-number world span mathematics, physics, engineering, economics, and statistics, where measurement, modeling, and
