An and expression contains two or more expressions. They are evaluated from left to right. If the first expression evaluates to false, the and expression immediately evaluates to false. If the first expression evaluates to true, the next expression is considered. If all expressions evaluate to true, the and expression evaluates to true. If any of the expressions evaluate to a value other than true or false, it is an error. Intermediate Student Language
