2. INTEGER A whole number; a number that is not a fraction. A thing complete In itself.

3. RATIONAL NUMBER Any number that can be made by dividing one integer by another. The word comes from “ratio”

4. SCIENTIFIC NOTATION Where a number is written in two parts

5. PERFECT SQUARE A number made by squaring a whole number

6. IRRATIONAL NUMBER A real number that cannot be written as a simple fraction - the decimal goes on forever without repeating.

7. REAL NUMBERS The type of number we normally use, such as 1, 15.82, -0.1, 3/4, etc… Positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers. They are called "Real Numbers" because they are not Imaginary Numbers.

8. DENSITY PROPERTY The density property tells us that we can always find another real number that lies between any two real numbers.

9. ADJACENT ANGLES Two angles are Adjacent if they have a common side and a common vertex (corner point), and don't overlap.

10. COEFFICIENT A number used to multiply a variable

11. DISTANCE FORMULA Any algebraic expression that gives the distance between two points in a particular coordinate system in a particular number of dimensions

12. DOMAIN Domain of a relation is the set of all x- coordinates of the ordered pairs of that relation.

13. HYPOTENUSE The longest side of a right triangle, opposite the right angle.

14. LEGS OF A RIGHT TRIANGLE In a right triangle, the sides opposite to the acute angles are called the Legs of a Triangle.

15. RATIONAL NUMBERS Any number that can be made by dividing one integer by another. The word comes from "ratio".

16. RANGE The range of a set of numbers is the highest number minus the lowest number

17. SLOPE The rate of change of a line. For any two points, it is the change in the y values divided by the change in the x values, and is referred to as the change in the rise over the change in the run of a line.

18. SCIENTIFIC NOTATION Where a number is written in two parts

19. PRISM A solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.

20. SCATTER PLOT A graph of plotted points that show the relationship between two sets of data.

21. SLOPE INTERCEPT FORM 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
