2.  A member of the set of positive whole numbers {1, 2, 3,... }, negative whole numbers {-1, -2, -3,... }, and zero {0}.

3.  A number that can expressed exactly by a ratio of two integers.

4.  A method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power, as 1385.62 written as 1.386 × 10 3.

5.  A rational number that is equal to the square of another rational number.

6.  A number that cannot be exactly expressed as a ratio of two integers.

7.  A rational number or the limit of a sequence of rational numbers, as opposed to a complex number.

8.  The property that states that there always exists another rational number between any two given rational numbers. This means that the set of rational numbers is dense.

9.  Two angles that have the same vertex and a side in common.

10.  a number or quantity placed (generally) before and multiplying another quantity, as 3 in the expression 3x.

11.  The distance between two points (x 1, y 1 ) and (x 2, y 2 ) in the Cartesian coordinate system can be given by: [(x 1 - x 2 ) 2 + (y 1 - y 2 ) 2 ] 1/2.

12.  The set of all possible input values for a function or relation.

13.  The side opposite the right angle in a right triangle.

14.  Either of the two sides that form the right angle in a right triangle or one of the two congruent sides in an isosceles triangle.

15.  A number that can be written as a fraction, or as finite or repeating decimals.

16.  The difference between the maximum and minimum values in a set of data.

17.  Another name for gradient.

18.  A method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power, as 1385.62 written as 1.386 × 10 3.

19.  A space figure with two parallel polygonal bases that are the same shape and the same size.

20.  Data that is plotted as points on a graph to show a possible relationship between two sets of data.

21.  the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.

22.  The magnitude of a number regardless of its sign. Hence, the absolute value of a number "n" is always positive or zero, written as |n|. When the number "n" is represented on a number line, its absolute value is the distance from the origin to that number.

23.  A number used to indicate the number of times a term is used as a factor to multiply itself. The exponent is normally placed as a superscript after the term.

24.  The result obtained when multiplying numbers, vectors, matrices, etc.

25.  A theorem stating that in a right triangle the area of the square on the hypotenuse is equal to the sum of the areas of the squares drawn on the other two legs.

26.  A triangle in which all three interior angles are acute (less than 90°).

27. The likelihood or chance of a given event happening. It is often expressed as a fraction or decimal. The probability that m particular events will occur out of a total of n possible events is m/n. A certainty means that, out of n possible events, all the events (n events) will happen. Therefore, a certainty has a probability of 1 (n/n = 1). Similarly, an impossibility has a probability of 0 because none will happen out of the total n possible events (0/n = 0).

28.  A number that can divide into another number with no remainder.

29.  A symbol that stands for an unknown quantity. When we make a mathematics equation out of an ordinary statement by using a variable(s), it makes the thinking process mechanized and automatic, thus making the solution process much easier.

30.  Find the value of an algebraic expression by replacing the variable(s) with the correct numerical value(s) to perform the operation.

31.  The number resulting from division.

32.  An angle with a measure between 0° and 90°.

33.  Planar figures or solid shapes that have the same shape and size.

34.  A number related to another in such a way that when these two numbers are multiplied together their product is 1.

35.  A point at which the two rays of an angle meet or the intersection point of two sides of a plane figure.

36.  A closed plane figure bounded by at least three line segments.

37.  A triangle having no two sides equal.

38.  The surface included within a closed figure, measured by the number of square units needed to cover the surface.

39.  The length of the boundary around a shape or a figure.

40.  The boundary line of a circle or the length of such a boundary line.

41.  An angle that is between 90° and 180°.

42.  A pair of angles that add up to 90°.

43.  A eight-sided polygon. A regular octagon is a polygon that has eight equal sides and eight equal angles.

44.  A polygon with five sides.

45.  A triangle one of whose interior angles is 90°.

46.  A four-sided plane figure whose four sides are equal.

47.  The numerator and denominator of a fraction that have had all common factors but 1 factored out and canceled.

48.  A line about which a curve or an object may rotate or revolve.
