"Always Three" Refactoring Challenge #1

always_three.rb

# 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

# (Refactoring script) Need to refactor using only two variables. I took out the ii_number variable from the old version and left with i_number and fin_number. Maybe...
fin_number = i_number

# add 5
fin_number+=5

# multiply by 2
fin_number*=2

# subtract 4
fin_number-=4

# divide by 2
fin_number/= 2

# subtract i_number from fin_number
fin_number-=i_number

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