The Language of Logic

Boolean expressions are how we write logic in text form, like algebra for true/false values. Instead of drawing circuit diagrams, we can write "A AND B" or "NOT(A OR B)". Named after George Boole, who invented this mathematical logic in the 1800s - long before computers! His maths became the foundation of all digital computing. Every IF statement you write is a Boolean expression.
