What do 0 and 1 usually mean in Boolean algebra?

They represent false and true, respectively; they are logical values rather than ordinary numbers in every context.

What are the three basic Boolean operators?

Conjunction (AND, $\wedge$), disjunction (OR, $\vee$), and negation (NOT, $\neg$).

What was George Boole's contribution?

He introduced an algebraic treatment of logic in 1847 and developed it further in his 1854 work on the laws of thought.

How does an indicator function encode a set?

For a subset $F$ of $E$, it returns 1 when an input element belongs to $F$ and 0 when it does not.

Summary

Boolean algebra provides a precise way to describe reasoning with true and false values. Unlike ordinary algebra, which usually works with numbers and arithmetic, Boolean algebra works with truth values and logical operations.

Boolean algebra is a branch of algebra and mathematical logic that formalizes operations on truth values. Its variables typically take values from the set $\{0,1\}$ , where 0 represents false and 1 represents true.
