(and EXPRESSION EXPRESSION EXPRESSION ...)
An 'and' expression contains two or more expressions. They are evaluated from the left. 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 considered an error. Beginning Student Table of Contents
