conjunction (Definition)

A conjunction is true only when both parameters (called conjuncts) are true. In English, conjunction is denoted by the word “and”. Symbolically, we represent it as $ \land$ or multiplication applied to Boolean parameters. Conjunction of $ a$ and $ b$ would be written

$\displaystyle a \land b$
or, in algebraic context,
$\displaystyle a \cdot b $
or
$\displaystyle ab $
The truth table for conjunction is
$ a$ $ b$ $ a \land b$
