You can also do exercises from Sections 1.1 – 1.7 of Hammack.

The example sheet doesn’t contain too many with pictures. Look at Hammack, Section 1.2 Exercises part B, Figures 1.2, 1.4, 1.5, 1.6. In class, for example, we drew some pictures in the real Cartesian plane (a square, a disc, a line), and asked whether they were Cartesian products or not. Don’t forget about these types of sets.

Here’s a reminder of the material:

basic definitions including set, element, equality, empty set, cardinality, subset

Set-builder notation and interval notation

ordered pairs, Cartesian products and powers, subset and powersets, including cardinality of such

operations (union, intersection, difference), universe, complement, Venn diagrams to visualize these
