Algebra Is a language of symbols,including variables.
Algebraic expressions are combinations of variables, numbers,and at least one operations.
Area the number of square units needed to cover a surface.
Base is the number used as a factor.
Composite number is a number greater than 1 with more than two factors.
Cubed the product in which a number is a factor three times.
Defining the varible is when you write a function rule that represent a real-word situation, you fist choose a varible to represent the input.
Equals sign a symbol of equality,=.
Equation a mathematical sentence that contains an equal sign,=.
Evaluate to find the value of something
Exponent indicates how many times the base number is used as a factor.
Factor the product multipling two or more numbers.
Formula an equation that shows a relationship among certain quantities.
Function the relationship that assigns exactly one output value to one input value.
Function rule describes the relationship between each input and output.
Function table a table organizing the input, rule, and output of a function
Numerical expression a combination of numbers and operations.
Order of operation tells you which operation to perform first so that everyone finds the same value for an expression.
Power numbers expressed using exponents
Prime factorization expressing a composite number as a product of prime numbers
Prime number a whole number that has exactly two unique factors, 1 and itself.
Solution the value for the variable
Solve to replace a variable with a value that results in a true sentence.
Squared a number multiplied by itself.
Varible a symbol, usually a letter, used to represent a number.
Average the sum of two or more quantities divided by the number of quantities; the mean.
Bar graph a graph using bars to compare quantities. The height or length of the bar represents a designated number.
Frequency is the number of times an item occurs.
Graph is a visual way to display data.
Horizontal axis the axis on which the categories or values are shown in a bar and line graph
Integers are positive whole numbers, their opposites, and zero.
Key explains the stem and the leaves in a stem-and-leaf plot
Line graph is used to show how a set of data changes over a period of time.
Line plot a diagram that shows the frequency of data on a number line.
Mean the sum of the data divided by the number of pieces of data.
Measures of central tendency the mean, median, and mode because they describe the center of a center of a set of data.
Median the middle number of the ordered data when there is a odd number of data, or the the mean of the middle two numbers when there are an even number of data.
Mode the number or numbers that occur most often.
Negative numbers numbers that are less than zero.
Opposites are numbers that are the same distance from zero in the opposite directions.
Outlier values that are much bigger or lower than others in a data set.
Positive numbers data that are greater than zero
Range the difference between the greatest and the least values of the set.
Stem-and-leaf plot the data is ordered from least to greatest and organized by place value.
Vertical axis the axis on which the scale and interval are shown on in a bar graph.
