  1. 1. value: a number’s distance from zero on a number line. Absolute value is never negative.
  2. 5. fraction: A fraction in which the numerator is equal to or greater than the denominator
  3. 7. property: multiplying each term in a sum or difference by a common factor does not change the change the value of the expression.
  4. 11. numbers: are the same distance from zero but in opposite directions.
  5. 12. a letter that represents an unknown number (or more than one number).
  6. 15. the result of subtraction.
  7. 16. an expression with a base and an exponent.
  8. 17. number: include decimals and fractions.
  9. 18. the product of a given number and any other whole number.
  10. 19. the product of a given number and any other whole number.
