What to Focus On

  • A set is a well-defined collection of objects.
  • Sets are written using capital letters; elements are written using small letters.
  • ∈ means belongs to and ∉ means does not belong to.
  • Roster form lists all elements inside braces.
  • In roster form, order does not matter.
  • In roster form, repeated elements are not written again.
  • The empty set contains no element.
  • The empty set is finite and has cardinal number 0.
  • A singleton set has exactly one element and cardinal number 1.

Common Mistakes to Avoid

An element and a subset mean the same thing.

Any collection is a set if it sounds familiar or important.

Order and repetition matter in roster form.
