On Monday and Tuesday in Renata's class we learned about truth tables.
Since mathematicians are lazy, we abbreviate whole statements by single letters:
A "Maria has a purple pencil."
B "Alec has a blue pencil."
Then we use a truth table to examine what happens if each statement is true or false. The tilde (~) is used to mean "not" or "negation."
