# You are now at the Always 3 script. It's in Ruby, girl. Hello and welcome!

# Ask the person (user) to provide a number. Any number.
puts "Please, give me your number, I mean A number!"

# Hint: use 'gets' method, convert to an integer using 'to_i', make it a variable
i_number = gets.to_i

# add 5
ii_number = i_number + 5

# multiply by 2
ii_number = ii_number * 2

# subtract 4
ii_number = ii_number - 4

# divide by 2
ii_number = ii_number / 2

# subtract i_number from ii_number
fin_number = ii_number - i_number

# show fin_number back to person/user
puts "You know what it is! #{fin_number}, of course!"
