Key Concepts

Hyperreal Numbers

Hyperreal numbers extend the real numbers by including infinitesimally small and infinitely large numbers. In many non?standard analyses, every real number is considered a hyperreal, but the hyperreal system also provides a rigorous framework for working with quantities that are infinitely close to a real number.

Real Numbers

The real numbers include every number that can occupy a position on the number line, comprising both rational numbers and irrational numbers. This set includes all the numbers used in everyday calculations, whether they are expressible as a fraction or not.

Rational Numbers

Rational numbers are those numbers that can be expressed as a fraction of two integers, with a non-zero denominator. This set includes integers, finite decimals, and repeating decimals, reflecting any number whose decimal representation either terminates or eventually repeats.

Natural Numbers

Natural numbers are the set of positive integers that are typically used for counting. They usually start at 1 (though some definitions include 0) and do not include fractions, decimals, or negative numbers.

Whole Numbers

Whole numbers consist of all natural numbers along with 0. They are the non?negative integers and form the basis for many counting and ordering processes.

Integers

Integers include all whole numbers as well as their negative counterparts. This set embraces ... -3, -2, -1, 0, 1, 2, 3, and so on, encompassing both positive and negative whole numbers without fractions or decimals.
