College Algebra: R.1.4 Work with Properties of Real Numbers

  1. states that a number equals itself: That is, a=a
    Reflexive Property
  2. States tha if a=b, then b=a
    symmetric Property
  3. states that if a=b and b=c, then a =c.
    transitive property
  4. states that if a=b, then we may substitute b for a in any expression containing a.
    Principle of substitution
  5. states the the order in which addition or multiplication takes place does not affect the final result.

    Commutative property
  6. states The way we add or multiply three real numbers does not affect the final result. Expressions such as 2+3+4 and 3*4*5 present no ammbiguity, even though addition and multiplication are performed on one pair of numbers at a time.
    Associative Properties.
  7. What Property is this?

    Distributive Property
  8. What property is this? 

    • Identity Properties
    • We call the 0 the addtitive identity and the 1 the multiplicative identity.
  9. the real numbers 0 and 1 have unique properties called ?
    Identity properties
  10. For each real number a, there is a real number -a, called
    additive inverse of a
  11. What property is this?

    Additive INverse property
  12. Finding an Additive inverse


    the use of the term 'negative" can be dangerous instead use minus
  13. for each nonzero real number a, there is a real number 1/a, called the
    Multiplicative inverse
  14. What property is this?

    Multiplicative inverse property
  15. The multiplicate inverse 1/a of a nonxzero real number a is also referred to as the ?
    Reciprocal

    *the number 0 has no reciprocal.
  16. Finding a reciprocal.

  17. a-b, also read "a less b" or "a minus b," is defined as?

    Difference
  18. if b is a nonzero real number, 

    "a divided by b" or "the ratio of a to b" is defined as?

    Quotient
  19. Working with differences and quotients

    what are the division properties for a nonzero number a.?
