A is not equal to B
Subset
$$A \not\subseteq B$$
A is not a subset of or equal to B
Superset
$$A \not\supseteq B$$
A is not a superset of or equal to B
Intersection
$$A \cap B =$$
{ }
Union
$$A \cup B =$$
{ hope, pray, preview, question, read, repeat if necessary, summarize, test }
Symmetric Difference
$$A \ominus B =$$
{ hope, pray, preview, question, read, repeat if necessary, summarize, test }
Difference
$$A - B =$$
{ preview, question, read, summarize, test }
Difference
$$B - A =$$
