If the value of age is under 18, the string is printed to the screen.
age = 10 puts "You"re too young to use this system" if age < 18 age = 10 if age < 18 puts "You"re too young to use this system" end

age = 24 puts "You"re a teenager" if age > 12 && age < 20
test for equality:
age = 24 puts "You"re 24!" if age == 24
