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 |
