- 3. the complete set of possible values of the independent variable in a function.
- 4. a mathematical sentence stating that two ratios are equal.
- 6. the number (1). The product of a number and the multiplicative identity is the number itself (e.g., 5x1=5).
- 11. any of the four regions formed by the axes in a rectangular coordinate system.
- 12. a ratio that compares two quantities of different units (e.g., feet per second).
- 13. the complete set of all possible resulting values of the dependent variable of a function.
- 14. a number, letter, point, line or any other object contained in a set.
- 15. a number that is the result of subtraction.

- 1. the result of multiplying numbers together.
- 2. any two numbers with a product of 1 (e.g., 4 and 1/4). Zero (0) has no multiplicative inverse. Also called a reciprocal.
- 5. the ratio of change in one quantity of the corresponding change in another quantity.
- 7. a form of a linear equation, y-y1 = m(x-x1), where m is the slope of the line and (x1, y1) is a point on the line.
- 8. a mathematical sentence in which two expressions are connected by an equality symbol.
- 9. the product of a number and the sum or difference of two numbers is equal to the sum or difference of the two products [e.g., x(a + b) = ax+bx].
- 10. the comparison of two quantities (e.g., the ratio of a and b is a:b or a/b, where b does not equal 0).
- 11. the result of dividing two numbers.
