#1.5B
use the set notation \(∪\), \(∩\), \(∈\) and \(∉\)
\(ε =\) universal set
\(∅ =\) empty set
#1.5C
understand the concept of the universal set and the empty set and the symbols for these sets
#1.5D
understand and use the complement of a set
Use the notation \(A'\)
#1.5E
use Venn diagrams to represent sets
