| absolute value | the distance the number is from 0 on the number line |
| distributive property | when a single-term expression is being multiplied by a sum or difference, the single-term expression can be multiplied by each term before finding the sum or difference. |
| additive inverse | an expression can be added to a given expression so that their sum is 0. |
| counting number | any number from a set of numbers represented by 1,2,3 etc. AKA natural number or positive integer. |
| coefficent | the constant by which a variable is multiplied |
| algebraic expression | a mathmatical expression that contains 1 or more variables |
| box-and-whisker plot | a rectangle (the box) is used to represent the dispersion of points between the first and third quartiles, and line segments (the whiskers) are used to represent the dispersion of points between the minimum value and the first quartile and between the maximum value and the first quartile. A line segment drawn within the box represents the medium value. |
| combination | a unique set or group of objects, symbols, numbers, etc. only the contents of the set, not the order or arrangement, determine a combination. |
| greatest common factor (GCF) | the greatest factor that 2 or more numbers have in common. |
| interquartile range | the difference between the third quartile and the first quartile in an ordered set of numerical data. |
| degree (temperature) | a unit of measure for temperature. |
| dependent variable | the variable in relation that represents a value determined by the independent variable. |
| expression | a number or variable, the power of a number or variable, or the sum, difference, product, or quotent of a combination of numbers, and/or powers of a number or variable. |
| histogram | a type of data display that represents a frequency distribution. |
| inequality | a mathmatical sentence that contains an inequality symbol. It compares 2 quantities. |
| independent variable | the variable that is used to determine the value of a relation. |
| irregular polygon | a polygon that does not have all congruent sides and all congruent angles. |
| least common multiple (LCM) | the least whole number that is a common mutiple of 2 or more numbers. |
| magnitude | A scalar (no units assigned) associated with a quantity |
| maximum | the greatest number in a set of data. |
| mean | a number found by dividing the sum of a set of numbers by the number of addendes |
| mean absolute deviation | the average of differences between each data point in a data set and the mean. |
| measures of center | statistical measures that are intended to provide numerical representations of the center of a set of numerical data. |
| measures of variability | statistical measures that are intended to provide numerical representations of the variability of a set of numerical data |
| opposite (of a number) | the additive inverse of a number |
| positive number | a number greater than 0 |
| minimum | the least number in a set of data |
| median | the middle number in a set of data ordered from least to greatest. |
| mode | the number that occurs most often in a set of data |
| net | a two dementional shape or figure that can be folded to form a 3 dementional shape or object. |
| negative number | any number less than 0 |
| permutation | an ordered arrangment or a set of elements. |
| proportion | an equation showing the equality of 2 ratios |
| proportional relationship | relationships between 2 variable quantities in which their ratio remains equivalent. |
| quartile | 1 of 3 values that divides a set of ordered data into 4 equal parts. |
| range (of data) | the difference between the greatest and the least values in a set of data. |
| rate | a ratio that compares 2 quantitites with different measurements. rate is a measure of change. |
| ratio | a comparison of 2 numbers, quantities, or expressions by division. |
| surface area | the sum of the areas of all the faces of a three dimensional (solid) figure or object. |
| trapezoid | a quadrilateral with exactly one pair of parallel |
| stem-and-leaf plot | a plot that represents discrete numerical data. In the display, a bar separates common digits and larger place value from the smaller digits. |
| unit rate | the ratio of a quantitiy to a single unit of comparison. |
| variable | a letter or symbol that represents a missing or unknown value. |
| rational number | any number that is equivalent to a fraction written as an integer over a counting number. |
