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.
