  1. 2. overlapping region; numbers that are solutions to both inequalities of a compound inequality
  2. 3. A decimal that repeats a digit or group of digits forever.
  3. 4. The property that says that two or more numbers can be added or multiplied in any order without changing the result.
  4. 5. combined regions; numbers that are solutions to either part of the compound inequality.
  5. 7. equation that is not true for any value of the variable
  6. 10. letter or symbol used to represent a value that can change.
  7. 12. expression written with a base and an exponent
  8. 14. A combination of variables, numbers, and at least one operation.
  9. 17. the number used as a factor in a power
  10. 19. Any number that can be expressed as a fraction
  11. 21. a number multiplied by itself to form a product
  12. 22. two numbers that have the same absolute value but have different signs; sum is 0
  13. 24. A mathematical statement that two expressions are equal.
