1. Real numbers: All four operations for the integers (+,-,*,/) Pencil and paper algorithms for all four operations Rational numbers Real numbers can be derived by infinite series of fractions such that the difference between fractions arbitrary distances apart tends to zero. This is ... [100%] 2024-01-04 [Arithmetic] [Real numbers]...
2. Real Numbers: The real numbers are a set of numbers with extremely important theoretical and practical properties. They can be considered to be the numbers used for ordinary measurement of physical things like length, area, weight, charge, etc. [100%] 2023-12-02
3. Positive real numbers: In mathematics, the set of positive real numbers, R > 0 = { x ∈ R ∣ x > 0 } , {\displaystyle \mathbb {R} _{>0}=\left\{x\in \mathbb {R} \mid x>0\right\},} is the subset of those real numbers that are greater than zero ...

4. Positive real numbers: In mathematics, the set of positive real numbers, \displaystyle{ \R_{\gt 0} = \left\{ x \in \R \mid x \gt 0 \right\}, }[/math] is the subset of those real numbers that are greater than zero.

5. Construction of the real numbers: In mathematics, there are several equivalent ways of defining the real numbers. One of them is that they form a complete ordered field that does not contain any smaller complete ordered field.

6. Completeness of the real numbers: Completeness is a property of the real numbers that, intuitively, implies that there are no "gaps" (in Dedekind's terminology) or "missing points" in the real number line. This contrasts with the rational numbers, whose corresponding number line has a ... [63%] 2023-12-14 [Real numbers]
7. Axiomatic introduction to the Real Numbers: I am sure that you probably know, intuitively, about the Real Numbers. However, this resource will disregard intuition of the Real Numbers, and will give a formal, Axiomatic approach to the Real Numbers. [57%] 2023-12-03 [Real numbers] [Mathematical analysis]...
