Divisibility rule
A divisibility rule is a shorthand way of discovering whether a given number is divisible by a fixed divisor without performing the division, usually by examining its digits. Although there are divisibility tests for numbers 
Iraqi mathematics
Iraqi mathematics, or Mesopotamian mathematics, refers to the history of mathematics in Iraq, also known as Mesopotamia, from ancient Sumerian and Babylonian mathematics through through to medieval Islamic mathematics. Babylonian mathematics (also known as Assyro 
Intermediate mathematics/Functions
From Wikipedia:Function (mathematics) In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An 
Intermediate mathematics/Numbers
The basis of all of mathematics is the "Next" function. See Graph theory. We might express this by saying that One differs from nothing as two differs from one. This defines the Natural numbers (denoted 
Intermediate mathematics/Physics
In the four rules, as they came finally to stand in the 1726 edition, Newton effectively offers a methodology for handling unknown phenomena in nature and reaching towards explanations for them. Classical mechanics

Polyhedron
A polyhedron is any threedimensional figure with flat surfaces that are polygons. Specifically, any geometric shape existing in threedimensions and having flat faces, each existing in twodimensions, which intersect at straight, linear 
Logic

Egyptian mathematics
Egyptian mathematics refers to the style and methods of mathematics performed in Egypt. See also: History of mathematics Predynastic Egypt of the 5th millennium BC pictorially represented geometric spatial designs. 
Cardinal number
This article is about the mathematical concept. For number words indicating quantity ("three" apples, "four" birds, etc.), see Cardinal number (linguistics). In mathematics, cardinal numbers, or cardinals for short, are a generalization of the natural 
Hellenistic mathematics
The Hellenistic period began in the 4th century BC with Alexander's conquest of the Eastern Mediterranean, including Egypt, as well as Mesopotamia and the Iranian plateau. Greek became the language of scholarship throughout the 
History of logic
The history of logic is the study of the development of the science of valid inference (logic). Many cultures have employed intricate systems of reasoning, and logical methods are evident in all human thought. An 
Ptolemy

Dimensional analysis
In physics and all science, dimensional analysis is a tool to find or check relations among physical quantities by using their dimensions. The dimension of a physical quantity is the combination of the basic physical 
Law of cosines
This article is about the law of cosines in Euclidean geometry. For the corresponding theorem in spherical geometry, see law of cosines (spherical). For the corresponding theorem in hyperbolic geometry, see law of cosines (hyperbolic 
Ellipse
In mathematics, an ellipse (Greek ἔλλειψις (elleipsis), a'falling short') is the finite or bounded case of a conic section, the geometric shape that results from cutting a circular conical or cylindrical surface with an 
Platonic solid
In geometry, a Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of 
Sphere
A sphere (from Greek σφαίρα — sphaira, "globe, ball," ) is perfectly round geometrical object in threedimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is 
Mathematical physics
Mathematical physics is the scientific discipline concerned with the interface of mathematics and physics. There is no real consensus about what does or does not constitute mathematical physics. A very typical definition is the one 
Modular arithmetic
Modular arithmetic (sometimes called clock arithmetic) is a system of arithmetic for integers, where numbers "wrap around" after they reach a certain value—the modulus. The Swiss mathematician Leonhard Euler pioneered the modern approach to 
Polygon
In geometry, a polygon is a plane figure bounded by a finite sequence of line segments, a twodimensional polytope. The line segments that make up the polygon are called sides; their intersections are called
