    The Rhind Mathematical Papyrus ( RMP; also designated as papyrus British Museum 10057, pBM 10058, and Brooklyn Museum 37.1784Ea-b) is one of the best known examples of ancient Egyptian mathematics. It is one of two well-known mathematical papyri, along with the Moscow Mathematical Papyrus. The Rhind Papyrus is the larger, but younger, of the two..

    en.wikipedia.org/wiki/Ancient_Egyptian_mathematics

    An interesting feature of ancient Egyptian mathematics is the use of unit fractions. [7] The Egyptians used some special notation for fractions such as ⁠ 1 / 2 ⁠, ⁠ 1 / 3 ⁠ and ⁠ 2 / 3 ⁠ and in some texts for ⁠ 3 / 4 ⁠, but other fractions were all written as unit fractions of the form ⁠ 1 / n ⁠ or sums of such unit ...

  5. Silver ratio - Wikipedia

    en.wikipedia.org/wiki/Silver_ratio

    The silver ratio is a Pisot–Vijayaraghavan number (PV number), as its conjugate 1 − √ 2 = ⁠ −1 δS⁠ ≈ −0.41421 has absolute value less than 1. In fact it is the second smallest quadratic PV number after the golden ratio. This means the distance from δ n. S to the nearest integer is ⁠ 1 δ n. S⁠ ≈ 0.41421n. Thus, the ...

    en.wikipedia.org/wiki/Fraction

    A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a / b or ⁠ ⁠, where a and b are both integers. [ 9] As with other fractions, the denominator ( b) cannot be zero. Examples include ⁠ 1 2 ⁠, − ⁠ 8 5 ⁠, ⁠ −8 5 ⁠, and ⁠ 8 −5 ⁠.

  7. Plastic ratio - Wikipedia

    en.wikipedia.org/wiki/Plastic_ratio

    The internal, coincident short edge of the medium rectangle and long edge of the small rectangle divides one of the square's other, two edges into two segments that stand to one another in the ratio ρ 4. The fact that a rectangle of aspect ratio ρ 2 can be used for dissections of a square into similar rectangles is equivalent to an algebraic ...

    en.wikipedia.org/wiki/Rhind_Mathematical_Papyrus...

    In this document a two-part set of fractions was written in terms of Eye of Horus fractions which were fractions of the form ⁠ 1 / 2 k ⁠ and remainders expressed in terms of a unit called ro. The answers were checked by multiplying the initial divisor by the proposed solution and checking that the resulting answer was 1/2 + 1/4 + 1/8 + 1/16 ...

  9. Supergolden ratio - Wikipedia

    en.wikipedia.org/wiki/Supergolden_ratio

    In mathematics, the supergolden ratio is a geometrical proportion close to 85/58.Its true value is the real solution of the equation x 3 = x 2 + 1.. The name supergolden ratio results from analogy with the golden ratio, the positive solution of the equation x 2 = x + 1.
