Can be true or false (depending on the value of n) z is a positive number. This is an example of the liar paradox and is studied in the scholastic logic of insolubles. If true, find a value that would result in a false number sentence. I planned to use this vocabulary regularly to help students become familiar and comfortable with it, just as periodically throughout the lesson I interchanged “equation” with “mathematical sentence.”. A mathematical sentence is a sentence that states a fact or contains a complete idea. It only takes a minute to sign up. Hint: First, consider a slight variation: "This sentence is true." “You could put sixteen over two as the answer, and that would make it true.” As I wrote 16/2 on the board, several hands went up.
