What is Boolean Algebra?
Boolean algebra, a method for applying and studying mathematical logic, was created by George Boolean, an English mathematician. He wrote “An investigation into the law of thought” in 1854. This book outlined a theory of logic that uses symbols rather than words. Boolean algebra is a more algebraic approach to the subject.
