How do you do boolean algebra? - Answers

It is used in science and proofs of proofs in maths, taking an example: Hypothesis: Bananas are red. (There exists) x x (is an element of) Red (and) Banana Banana (implies) Red (not) Red (implies) (not) Banana If a yellow banana is found, (There exists) y y(is an element of)Banana (therefore) y(is an element of) Red There is a contradiction, as the banana must be red, but it is yellow. The above is not the only use, but Boolean algebra exclusively contains symbols of (not), (and), and (or).
