The definition of booleanBoolean algebra is the mathematics of base two numbers.
Since base two numbers have only two values, zero and
one, there is a good analogy between base two numbers and
the logical values "true" & "false". In
common usage, booleans are therefore considered to be simple
logical values like true & false and the operations that
relate them, most typically "and", "or" and
"not". Since everyone has a basic understanding of the
concepts of true & false and basic conjunctions, everyone
also has a basic understanding of boolean concepts  they
just may not realize it.
