A set $A$ is a subset of a set $B$, denoted by $A \subseteq B$, if every element of $A$ is also an element of $B$.
Proof techniques are used to establish the validity of mathematical statements. In computer science, proof techniques are used to verify the correctness of algorithms, data structures, and software systems. A set $A$ is a subset of a
A proposition is a statement that can be either true or false. A proposition is a statement that can be

A set is a collection of objects, denoted by $S = {a_1, a_2, ..., a_n}$, where $a_i$ are the elements of $S$.
A truth table is a table that shows the truth values of a proposition for all possible combinations of truth values of its variables.
