Rational Numbers  A number that is an integer or that can be expressed as a fraction whose numerator and denominator are integers, and whose denominator is not zero. Examples:  1, ^{1}/_{3}, ^{3}/ A, 9, 235.Rational numbers, when expressed as decimals, are recurring decimals or finite (terminating) decimals. Numbers that are not rational are irrational. Irrational numbers include V5 and n which produce infinite, nonrecurring decimals. 
Equation  A mathematical statement showing that two expressions are equal. The expressions are linked with the symbol = Examples: 7  2 = 4 + 1 4x = 3 x^{2}  2x + 1 = 0 
Axiom  A premise or starting point of reasoning. As classically conceived, an axiom is a premise so evident as to be accepted as true without controversy.^{[1]} The word comes from the Greek ?????? (axioma) 'That which is thought worthy or fit' or 'that which commends itself as evident. 
Whole numbers  The members of the set of positive integers including zero. They can as well be referred to simply as integers, or natural numbers. Examples of whole numbers include 1, 2, 3, 4, and 5. They are numbers which neither fraction nor decimal. 
Abstraction  he process of taking away or removing characteristics from something in order to reduce it to a set of essential characteristics. (From the Latin abs, meaning away from and trahere, meaning to draw). 
Multiplication  The operation of combining two numbers to give a third number, the product. Example: 12 x 3 = 36 is a multiplication. Multiplication can be seen as the process of repeated addition.Example: 3 x 5 = 3 + 3 + 3 + 3 + 3 = 15.Multiplication is the inverse operation of division, and it follows that 7 + 5 x 5 = 7Multiplication is commutative , associative and distributive over addition or subtraction. 
Hard (disk) drive  A common magnetic storage device that reads and writes data on metal disks inside a sealed case. 
Vehicle  Any device designed to transport people or cargo from one destination to another i.e. bicycles, cars, motorcycles, trains, ships, boats and aircraft. The word vehicle is derived from a Latin word vehiculum. Vehicles that do not travel on land are referred to as crafts. 
Hydraulics  A topic in applied science and engineering dealing with the mechanical properties of liquids. At a very basic level hydraulics is the liquid version of pneumatics. 
Calculus  The study of how things change. It provides a framework for modeling systems in which there is change, and a way to deduce the predictions of such models. 
Magnetism  A class of physical phenomena that includes forces exerted by magnets on other magnets. It has its origin in electric currents and the fundamental magnetic moments of elementary particles. These give rise to a magnetic field that acts on other currents and moments. 
Fragmentation  A database server feature that allows you to control where data is stored at the table level. Fragmentation enables you to define groups of rows or index keys within a table according to some algorithm or scheme. You can store each group or fragment (also referred to as a partition) in a separate dbspace associated with a specific physical disk. 
Graphic  A picture, drawing, animation or other type of image. 
Arithmetic and logic unit  The part of the CPU that performs the mathematical and logical operations. 
Theorem  A statement that has been proven on the basis of previously established statements, such as other theoremsand generally accepted statements, such as axioms. The proof of a mathematical theorem is a logical argument for the theorem statement given in accord with the rules of a deductive system.

Probability  A measure or estimation of likelihood of occurrence of an event. [1] Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen). [2] The higher the degree of probability, the more likely the event is to happen, or, in a longer series of samples, the greater the number of times such event is expected to happen. A simple example is a coin toss that has 0.5 or 50% chance of landing with the "head" side facing up. 
Subtraction  The renaming of a sum and an add end; the opposite of addition. 
Server  A main computer that provides a service on a network. 
Equality  A relationship between two quantities or, more generally two mathematical expressions, asserting that the quantities have the same value or that the expressions represent the same mathematical object. 
Triangle  One of the basic shapes in geometry: a polygon with three corners or vertices and three sides or edges which are line segments 
Real numbers  A number that is rational or irrational. Real numbers are those generally used in mathematics, science and everyday contexts. Numbers that are not imaginary, not connected with the square root of a negative number for instance. 
Function  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 example is the function that relates each real number x to its square x^{2}.

Irrational number  Any real number that can not be expressed as a ratio a / b, where a and b are integers and b is nonzero. 
Fraction  Represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, onehalf, eightfifths, threequarters. (From Latin: fractus, "broken") 
Kinematics  The branch of classical mechanics which describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion. The term is the English version of A.M. Ampere's cinematique, which he constructed from the Greek ??????, kinema (movement, motion), derived from ??????, kinein. 
CDROM  Abbreviation for compact disk read only storage device (a disk) that is read using laser light. 
Constant  A number or quantity that does not vary. Example: in the equation y = 3x + 6, the 3 and 6 are constants, where x and y are variables. 
Negligible  Refers to the quantities so small that they can be ignored (neglected) when studying the larger effect. Although related to the more mathematical concepts of infinitesimal, the idea of ??negligibility is particularly useful in practical disciplines like physics, chemistry, mechanical and electronic engineering, computer programming and in everyday decisionmaking. 
Corner  In elementary geometry, a point where two or more lines or line segments meet. More correctly called vertex, vertices (plural). Examples: a rectangle has four corners or vertices; and a cube has eight corners or vertices. 
Circular function  A term used to describe the cosine and sine functions in trigonometry. Sometimes used for other trigonometric functions which are respectively the x and y coordinates of a rotating point on a circle of unit radius, centred on the origin of coordinates. The term circular function is also used for other trigonometric functions that can be derived from the cosine and sine functions.
