Simple_addition Challenge Solution

for arg in ARGV
  file = File.open(arg)

  file.each_line do |line|

    if line.start_with?('.')
      line.gsub!(" ","+")
      line.gsub!(".","0.")
      puts eval line
    else

    line.gsub!(" ","+")

    puts eval line
    end
  end

end

Solution Notes:

The “if” statement catches any numbers that are in the form of a decimal and converts them into a float format.
