| Question | Answer |
|---|---|
| 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. |
