understand the definition of a set

use the set notation \(∪\), \(∩\), \(∈\) and \(∉\)

\(ε =\) universal set

\(∅ =\) empty set

understand the concept of the universal set and the empty set and the symbols for these sets

understand and use the complement of a set

Use the notation \(A'\)

use Venn diagrams to represent sets

understand sets defined in algebraic terms, and understand and use subsets

If \(A\) is a subset of \(B\), then \(A⊂B\)

use Venn diagrams to represent sets and the number of elements in sets

use the notation \(\text{n}(A)\) for the number of elements in the set \(A\)

use sets in practical situations
