Equality
$$A \neq B$$
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
$$A \cup B =$$
{ Assess, Execute, Plan, Re-evaluate, Stop, free flow, synchronized flow, wide moving jam }
Symmetric Difference
$$A \ominus B =$$
{ Assess, Execute, Plan, Re-evaluate, Stop, free flow, synchronized flow, wide moving jam }
Difference
$$A - B =$$
{ free flow, synchronized flow, wide moving jam }
Difference
$$B - A =$$
{ Assess, Execute, Plan, Re-evaluate, Stop }
Cartesian Product
$$A \times B =$$
{ (free flow, Assess),
(free flow, Execute),
(free flow, Plan),
(free flow, Re-evaluate),
(free flow, Stop),
(synchronized flow, Assess),
(synchronized flow, Execute),
