Free Boolean algebra

Free Boolean Algebra is a type of algebra where the numbers can only be either "yes" or "no", like in a computer. It uses symbols, like "+" and "*", to create equations that can be used to solve problems. For example, if you wanted to find out if it was raining outside, you could write an equation that said "If it is cloudy, then it is raining" (using the symbols "+" and "*"). If it is cloudy outside, then the equation would be true, and if it isn't then it would be false.
