Term | Definition |
---|---|

Difference | The answer when you subtract. |

Distributive Property | The sum of two addends multiplied by a number is the sum of the product of each addend and the number. a(b+c) = ab + ac |

Dividend | A number that is divided by another number. |

Divisor | A number by which another number is to be divided. |

Factors | Numbers that are being multiplied together |

Greatest Common Factor | The largest factor that two or more numbers have in common. |

Least Common Multiple | The smallest number that is the multiple of two or more other numbers. |

Percent | A fraction or ratio in which the denominator is 100 |

Product | The answer when you multiply |

Proportion | An equation which states that two ratios are equal. |

Quotient | The number resulting from dividing one number by another |

Rate | A comparison of two quantities that have different units of measure |

Ratio | compares quantities that share a fixed, multiplicative relationship. |

Rational number | A number that can be written as a/b where a and b are integers, but is not equal to 0. |

Reciprocal | Multiplicative inverse of a number (except zero) |

Sum | The answer when you add, the total amount |

Unit Ratio | are ratios written as some number to 1. Algebraic expression |

Associative Property | The sum or product of a set of numbers is the same no matter how the numbers are grouped. |

Coefficient | A number multiplied by a variable in an algebraic expression. |

Commutative Property | The sum or product of a group of numbers is the same regardless of the order in which the numbers are arranged. |

Cubed | A number to the third power |

Distributive Property | The sum of two addends multiplied by a number is the sum of the product of each addend and the number. a(b+c) = ab + ac |

Equation | A mathematical sentence that contains an equal sign |

Exponent | The number of times a number or expression (called base) is used as a factor of repeated multiplication. Also called the power. |

Inequality | A mathematical sentence that contains the symbols >, <, ≥, or ≤. |

Inverse Operation | A mathematical process that combines two or more numbers such that its product or sum equals the identity. |

Like Terms | Terms in an algebraic expression that have the same variable raised to the same power. Only the coefficients of like terms are different. |

Order of Operations | The rules that tell which operation to perform first when more than one operation is used (PEMDAS) |

Term | A number, a variable, or a product of numbers and variables. |

Squared | a number to the second power |

Variable | A letter or symbol used to represent a number or quantities that vary Area |

Box and Whisker Plot | A diagram that summarizes data using the median, the upper and lowers quartiles, and the extreme values (minimum and maximum). |

Cubic Units | Measures the volume of solids |

Irregular Polygon | A polygon in which sides are not all the same length nor do the interior angles have the same measure. |

Lateral Faces | In a prism, a face that is not a base of the figure. |

Inter-Quartile Range (IQR) | The difference between the first and third quartiles. (Note that the first quartile and third quartiles are sometimes called upper and lower quartiles.) |

Mean Absolute Deviation | The average distance of each data value from the mean. It is a gauge of “on average” how different the data values are form the mean value. |

Mean | The “average” or “fair share” value for the data; add all the numbers and divide by how many numbers there are. |

Measures of Center | The mean and the median are both ways to measure the center for a set of data. |

Median | The value for which half the numbers are larger and half are smaller. If there are two middle numbers, it is the arithmetic mean of the two middle numbers. |

Mode | The number that occurs the most often in a list. There can be more than one or none. |

Net | A two-dimensional figure that, when folded, forms the surfaces of a three-dimensional object. |

Outlier | A value that is very far away from most of the values in a data set. |

Polygon | A number of coplanar line segments, each connected end to end to form a closed shape. |

Prism | A polyhedron with two parallel and congruent faces, called bases, and all other faces that are parallelograms. |

Range | A measure of spread for a set of data. To find the range, subtract the smallest value from the largest value in a set of data. |

Regular Polygon | A polygon that has all sides equal and all interior angles equal. |

Surface area | The total area of the 2-dimensional surfaces that make up a 3-dimensional object. |

Vertices | The common endpoint of two or more rays or line segments. |

Volume | The amount of space occupied by an object. Absolute Value |

Coordinates | used to show the position on a coordinate plane; the first number is x on the horizontal plane and the second number is y on the vertical plane. |

Customary System | the system of measurement used in the United States (cups, pints, quarts, gallons, pounds, inches, feet, yards, miles) |

Metric System | a measurement system used around the world based on the powers of ten (meters, liters, grams) |

Negative Numbers | a number less than zero |

Opposite Number | two numbers that have the same numeral but have opposite signs |

Ordered Pair | Used to indicate a point on a coordinate plane, graph, or map |

Origin | The point of intersection of the x and y axis on a coordinate plane (0,0) |

Positive Number | a number greater than zero |

Rational Number | a number that can be expressed as the ratio of two integers in the form a/b where b is not equal to 0. |

X-Axis | the horizontal axis of a graph |

X-Coordinate | the position of a point according to the x |

Y-Axis | the vertical axis of the graph |

Y-Coordinate | the position of point according to the y |
