# Math Vocab

TermDefinition
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
