I do not understand setbuilder notation.....
Using correct mathematical notation and symbols, express the following in setbuilder notation: Z = {16, 17, 18, 19, 20}

Instead of enumerating the members, the setbuilder notation defines the members of a set using mathematical conditions.
The set of all odd integers would be:
A={x∈ℤ : mod(x,2)≡1}
or the integers between 40 and 45:
B={x∈ℤ : 40≤x≤45}
For more examples, see:

x¡Êℤ : 9<x¡Ü20
