# Math Vocab

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

Term | in Algebra a term is either a single number or variable, or numbers and variables multiplied together. |

Coefficient | a numerical or constant quantity placed before and multiplying the variable in an algebraic expression |

Commutative Properties | the "Commutative Property" allows you to change the order in which two numbers are multiplied or added without changing the product or sum |

Associative Properties | the "Associative Property" allows you to change the grouping of numbers being multiplied or added without changing the product or sum |

Identity Properties | the "Identity Property" allows you to add 0 to addend without changing the addend and to multiply a factor by 1 without changing the factor |

Properties | statements that are true for any number |

Equivalent Expressions | the expressions 6*10 and 10*6 are called equivalent expressions because they have the same value |

Distributive Property | the Distributive Property states that to multiply a sum or difference by a number, multiply each term by the number outside the parentheses |

Factor the Expression | when numeric or algebraic expressions are written as a product of their factors |

Equation | an expression or a proposition, often algebraic, asserting the equality of two quantities |

Equals Sign | the symbol (=), used in a mathematical expression to indicate that the terms it separates are equal |

Solve | to work out the answer or solution to (a mathematical problem) |

Solution | the process of determining the answer to a problem or the answer itself |

Inverse Operations | the operation that reverses the effect of another operation |

Subtraction Property of Equality | if both sides of an equation have the same number subtracted from them, the equation is still equal |

Addition Property of Equality | if you add the same number to both sides of an equation, the sides remain equal |

Function | any mathematical condition relating each argument (input value) to the corresponding output value |

Function Rule | what relates the input value to the output value |

Function Table | displays the relationship between the inputs and outputs of a specified function |

Independent Variable | a variable (often denoted by x ) whose variation does not depend on that of another |

Dependent Variable | a variable (often denoted by y ) whose value depends on that of another |

Sequence | a list of numbers or objects in a special order |

Arithmetic Sequences | each term is equal to the previous term, plus (or minus) a constant |

Geometric Sequences | a sequence with the ratio between two consecutive terms constant |

Linear Function | any function that graphs to a straight line |

Polygon | a plane figure with at least three straight sides and angles, and typically five or more |

Congruent | (of figures) identical in form; coinciding exactly when superimposed |

Composite Figure | a figure (or shape) that can be divided into more than one of the basic figures |

Decompose | the process of separating numbers into their components (to divide a number into smaller parts) |

Three-Dimensional Figure | an object that has height, width and depth, like any object in the real world |

Volume | the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great |

Prism | a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms |

Cubic Units | a measure of volume |

Rectangular Prism | a solid figure where all sides are rectangles and all sides meet perpendicular |

Triangular Prism | a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides |

Surface Area | the area of such an outer part or uppermost layer |

Pyramid | a solid object with a polygonal base and triangular sides |

Slant Height | the altitude of a side of a regular pyramid |

Vertex | each angular point of a polygon, polyhedron, or other figure |

Lateral Faces | the face or surface of the sides of the solid |

Base | the lowest part or edge of something, especially the part on which it rests or is supported |

Measure Of Center | a value at the center or middle of a data set |

Median | the middle value |

Mode | the number that appears most often in a set of number |

Measures of Variation | either properties of a probability distribution or sample estimates of them |

Interquartile Range | a measure of statistical dispersion |

Quartiles | each of four equal groups into which a population can be divided according to the distribution of values of a particular variable |

Range | the area of variation between upper and lower limits on a particular scale |

First Quartile | the middle number between the smallest number and the median of the data set |

Outliers | a number differing from all other numbers of a particular group or set |

Third Quartiles | the middle value between the median and the highest value of the data set |

Mean Absolute Deviation | the average distance between each data value and the mean |

Line Plot | a graph that shows frequency of data along a number line |

Dot Plot | a statistical chart consisting of data points plotted on a fairly simple scale |

Histogram | a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval |

Frequency Distribution | a mathematical function showing the number of instances in which a variable takes each of its possible values |

Box Plot | a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum |

Distribution | the way in which something is shared out among a group or spread over an area |

Symmetric Distribution | the values of variables occur at regular frequencies, and the mean, median and mode occur at the same point |

Cluster | a group of similar things or people positioned or occurring closely together |

Gap | an unfilled space or interval; a break in continuity |

Peak | reach a highest point, either of a specified value or at a specified time |
