101 Properties of real numbers Part 2 101 Properties of real numbers Part 2 Presentation Transcript

  • Properties of Real Numbers Part 2 Rules that real numbers follow
  • Essential Question
    • What rules do real numbers follow?
  • Equality
  • Equality
    • Addition
    • If a=b, then
    • a+c=b+c
  • Equality
    • Subtraction
    • If a=b, then
    • a-c=b-c
  • Equality
    • Multiplication
    • If a=b, then
    • ac=bc
  • Equality
    • Division
    • If a=b, then
    • a/c=b/c
  • Substitution
    • If a = b, then a may be substituted for b.
  • Reflexive
    • A number equals itself
    • a = a
    • 3 = 3
  • Symmetric
    • If two things are equal, then the equation can be flipped.
  • Symmetric
    • If a = b, then b = a
    • 2x + 9 = 23 is the same as 23 = 2x + 9
  • Transitive
    • If a = b & b = c, then a = c
    • 4 = x & x = z, then . . .
    • z = 4
  • Essential Question:
    • What rules do real numbers follow?
