| A | B |
|---|
| Base | The number in an exponential expression that is used as a factor. For Example, in 32 , 3 is the base |
| Bases of a prism | Two congruent and parallel faces of a prism |
| Best fit line | The line drawn through the points of a scatter plot that indicates the tendency of the data |
| Box-and-whiskers plot | A plot that separates the middle 50% of the data into a box with the median drawn inside as a vertical line. The remaining 50% of the data is shown as two lines, whiskers, to the left and right of the box. The whiskers represent the upper 25% and lower 25% of the data. The outer ends of the whiskers denote the maximum and minimum data points |
| 4-step Method | A method for a problem solving that can be used for any math problem |
| Absolute value | A number's distance from zero on a number line |
| Acute angle | An angle whose measure is between 0 and 90 degrees |
| Acute triangle | A triangle with three acute angles |
| Attend | A number being added to obtain a sum |
| Additive inverse | The opposite of a number in a addition operation. For example, for a number a, the additive inverse is -a, such that a + -a 0 |
| Algebra | A generalization of the concepts of arithmetic. In algebra, unknown numbers are called variables and are represented by letters |
| Algebraic expression | a combination of numbers and variables with one or more operations. |
| Angle | a figure formed by two rays with a common endpoint. |
| Area | The number of square units needed to cover a region. |
| Arithmetic sequence | A sequence of numbers in which the interval between each successive pair remains constant. |
| Associative Property of addition | The grouping of addends ded not change the sum. |
| Associative Property of Multiplication | The grouping of factors does not change the product. |
| Axes | The vertical and horizontal lines of reference that divide the coordinate plane into quadrants. |
| Axis | A reference line used to read information on a graph. |
| Bar Graph | A type of graph using vertical or horizontal bars to indicate relationships among data. |
