I was an airman in the United States Air Force, stationed at Keesler Air Force Base and studying to become a Radio Relay Equipment Repairman.

Boolean algebra is a branch of algebra in which the variables are truth variables, being true or false, and usually denoted as 1 or 0 respectively. Boolean algebra was invented by George Boole in his first book, entitled “The Mathematical Analysis of Logic”, copyrighted in 1947.
Boolean algebra has been fundamental in the field of digital electronics and is provided for in all modern programming languages. Boolean algebra is also used in the study of sets and statistics.
The screenshot below gives a fairly descriptive symbology of the main components used in Boolean algebra:-
The basic operations of Boolean algebra are composed of the symbololgy of AND, OR, and…
