Number

number is a primitive mathematical entity, whose concept arises from the need to count, as an abstraction of the concept of quantity, or to assign the position in a list of elements, or to identify the relationship between quantities of the same type.

Numerical sets (number systems)

Numbers can be classified into sets, called number systems:

  • Natural numbers (counting numbers) \(\mathbb{N}\)
  • Whole numbers
  • Integers \(\mathbb{Z}\)
  • Rational numbers \(\mathbb{Q}\)
  • Real numbers \(\mathbb{R}\)
  • Complex numbers \(\mathbb{C}\)
