The Basic set notation exercise appears under the High school statistics and probability Math Mission. This exercise introduces basic set notation and operations.
Types of Problems[]
There is one type of problem in this exercise:
- Find the set: This problem describes two sets in standard set-listing notation. The user is asked to perform an operation on the sets, either union, intersection or set-difference. They write the correct elements in the provided box separated by commas, or select empty set if appropriate.
Strategies[]
This exercise is easy to get accuracy badges and speed badges because there is only one type of problem and they can be performed fairly mechanically.
- Union, , means all elements in one set or the other.
- Intersection, , means all elements in one set and the other (simultaneously).
- The union operation will never have an answer of empty set because the initials sets are always non-empty.
- The order of elements in a set does not matter.
- On set-difference and union it is a good idea to just start concentrating on the first set and then throw additional ones as needed for union, or neglect the ones that taken out via set-difference.
Real-life Applications[]
- Set notation is a concept that makes exposition of other ideas easier, which require talking about collections and their properties thereof.
- Data and statistics appear in news reports and in the media every day.
- Statistics can be seen more frequently than calculus in every day life.
