| The set of numbers consisting of the positive numbers, the negative numbers, and zero. | Real Numbers |
| The point labeled zero on a number line. | Origin |
| Any of the numbers less than zero. | Negative Numbers |
| Any of the numbers greater than zero. | Positive Numbers |
| Any of the numbers.. -3,-2,-1,0,1,2,3.... | Integers |
| The point that corresponds to a number. | Graph of a number |
| Drawing a the point on a number line that corresponds to a number. | Plotting a point |
| Two points on a number lines that are the same distance from the origin but are on opposite sides of it. | Opposites |
| The distance between the origin and the point representing the real number. | Aboslute Value |
| The speed and direction in which an object is traveling (up is positive and down is negative). The speed of an object is the absolute value of its velocity. | Velocity |

| A measure of the likelihood that the event will occur due to chance. | Probability of an Event |
| The different possible results of a proablity experiment. | Outcomes |
| A type of probablity that is based on the number of favorable outcome divided by the total numbers of outcomes. | Theoretical Probabilty |
| The outcomes for a particular event that are being considered. | Favorable Outcomes |
| A probabilty that is based on repetitions of an actual experiment. | Experimental Probability |
