Across
- 1. numbers that correspond to points on a graph in the form
- 5. The horizontal and vertical number lines used in a rectangular graph or coordinate grid system.
- 7. The shape made by two rays extending from a common endpoint, the vertex. Measures of angles are described using the degree system.
- 8. The line or plane upon which a figure is thought of as a resting.
- 10. A collection of numbers, symbols, and/or operation signs that stands for a number.
- 13. A number or expression that divides exactly another number
- 14. measure Obtaining the measure of an object by using measuring devices, either standard devices of the customary or metric systems, or nonstandard devices such as a paper clip or pencil.
- 16. an expression
- 17. property The order in which two numbers are added or multiplied does not change their sum or product
- 18. The value of a variable when all other variables in the equation equal zero (0). On a graph, the values where a function crosses the axes.
- 20. The numbers in the set {...,-4, -3, -2, -1, 0, 1, 2, 3, 4,...}.
Down
- 2. A sentence that states one expression is greater than or equal to, less than, less than or equal to another expression (e.g., a does not = 5 or x < 7 ).
- 3. value: A number's distance from zero on a number line.
- 4. numbers for the variables and follow the operation symbols to find the numerical value of the expression.
- 6. The point at which two lines meet.
- 9. Any part of a whole is called a fraction (e.g., one-half written in fractional form is 1/2.
- 11. The number of times the base occurs as a factor. For example, 2^3 is the exponential form of 2x2x2. The numeral two is called the base, and the numeral three is called the exponent.
- 12. the fact or condition of functioning or being active.
- 15. able to assume different numerical values.
- 19. equation A mathematical sequence in which two expressions are connected by an equality symbol.
