The students use truth tables to solve problems such as:
You travel to an island occupied by Knights (who always tell the truth) and Knaves (who always lie). You meet 3 natives: Adam, Bob and Carlos.
- Adam says, "."
- Bob says, "."
- Carlos says, "."

Which of the 3 natives are Knights and which are Knaves?
