  • How do you know if two rational numbers are reciprocals of each other?
    Their product is 1.
  • If you multiply a rational number by itself three times, what is this operation called?
    Raising to the third power (or cubing).
  • If two lines never meet no matter how far they are extended, what are they called?
    Parallel lines.
  • What do we call the common point where two rays meet to form an angle?

  • What happens to the sign when you multiply two rational numbers with different signs?
    The result is negative.
  • When a negative rational number is raised to an even power, will the result be positive or negative?
    Positive.
  • Can an irrational number be converted into a simple fraction?
    No, it cannot.
  • What must be the same before adding two rational numbers with denominators?
    Their denominators must be the same.
