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
$$A \cup B =$$
{ concomitant variations, difference, direct agreement, joint agreement and difference, meiosis, mitosis, residue }
Symmetric Difference
$$A \ominus B =$$
{ concomitant variations, difference, direct agreement, joint agreement and difference, meiosis, mitosis, residue }
Difference
$$A - B =$$
{ meiosis, mitosis }
Difference
$$B - A =$$
{ concomitant variations, difference, direct agreement, joint agreement and difference, residue }
Cartesian Product
$$A \times B =$$
{ (meiosis, concomitant variations),
(meiosis, difference),
(meiosis, direct agreement),
(meiosis, joint agreement and difference),
(meiosis, residue),
(mitosis, concomitant variations),
(mitosis, difference),
(mitosis, direct agreement),
(mitosis, joint agreement and difference),
(mitosis, residue) }
