2.  Any whole number and/or the additive inverse of a whole number is an integer

3.  A number that can be written as a fraction, or as finite or repeating decimals. The square root of 2 (1.414 213 6...) is not a rational number.

4.  A representation of very large or very small numbers as the product of two factors: a × 10 n, where 1 < a < 10.For example, the speed of light, 299,790,000 (m/s), can be written as 2.9979×10 8 (m/s).

5.  A number whose square root is an integer.For example, 4 is a perfect square because its square root is the integer 2.

6.  A number that cannot be expressed as a fraction. Examples include some square roots such as 2 1/2 and 3 1/2, and numbers such as (the ratio of the circumference of a circle to its diameter).

7.  All the numbers that includes all rational and irrational numbers.

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 share the same vertex and have one side in common between them.

10.  The number part in front of the non- numerical symbol(s) in an algebraic expression, signifying multiplication. For example, the number 4 in the expression 4xy is a coefficient.

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. The square root of 2 (1.414 213 6...) is not a rational number.

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

17.  Another name for gradient.

18.  A representation of very large or very small numbers as the product of two factors: a × 10 n, where 1 < a < 10.For example, the speed of light, 299,790,000 (m/s), can be written as 2.9979×10 8 (m/s).

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.  An algebraic equation, such as y = 2x + 7 or 3x + 2y - z = 4, in which the highest degree term in the variable or variables is of the first degree. The graph of such an equation is a straight line if there are two variables.
