Chaining together multiple comparisons is also possible with a clever use of parentheses:


age = 24
gender = "male"

puts "You're a working age man" if gender == "male" && (age >= 18 && age <= 65)

1.	the && operator means "and."
2.	have more than two statements separated by &&
3.	use the keyword and instead of &&.
4.	\|\| operator is or.
5.	check whether one or the other is true by using \|\|
6.	Are more than two statements OK?
7.	And, or and Not
8.	Use or in if statement
