6th EQUATIONS AND EXPRESSIONS COMMON CORE - COMPLETE
| Term | Definition |
|---|---|
| exponent | this says how many times to use that number in a multiplication. It is written as a small number to the right and above the base number. |
| base | The number that is going to be raised to a power |
| numerical expressions | a mathematical phrase that contains numbers and operations. |
| algebraic expressions | a mathematical phrase. contains numbers, operations and variables. |
| evaluate | To calculate the value of. |
| sum | The result of adding two or more numbers; the answer to an addition problem. |
| term | In Algebra, a single number or variable, or numbers and variables multiplied together. |
| product | The answer when two or more numbers are multiplied together. |
| factor | numbers we can multiply together to get another number |
| quantity | How much there is of something. |
| quotient | The answer after you divide one number by another; dividend ÷ divisor = _____________________________ |
| coefficient | A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a ___________________ |
| constant | A fixed value. In Algebra, a _________________ is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are ______________. If it is not a _________________it is called a variable. |
| like terms | Terms whose variables (and their exponents such as the 2 in x2) are the same. Example: 7x and 2x are ______________ because the variables are both "x" |
| equivalent expressions | equations that have the same solution. |
| variable | A symbol for a number we don't know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the_____________. |
| inequalities | the relation between two expressions that are not equal,; the symbol is ≠ |
| equation | says that two things are equal. It will have an equals sign "=" like this: 7 + 2 = 10 − 1 |
| > | greater than |
| The symbol < | less than. |
| ≥ | greater than or equal to |
| ≤ | less than or equal to |
| profit | Income less all expenses. Example: Sam's Bakery received $900 yesterday, but expenses such as wages, food and electricity came to $650. So the______________ was $900 − $650 = $250. |
| exceed | To be greater than, as in number or degree; surpass: |
| dependent variables | The "output" value of a function. example: y = x2; y is the ______________________________. |
| independent variables | An "input" value of a function. Example: y = x squared; x is an Independent Variable |
| discrete data | Data that can only take certain values. For example: the number of students in a class (you can't have half a student). |
| continuous data | Data that can take any value (within a range) Example: People's heights could be any value (within the range of human heights), not just certain fixed heights. |
