Hi all,

So these are the example files that I have. I actually have thousand of lines of data in each files. To make it easier to read, I shorten it.

File_1
Item              Availability       Broken
Laptop_Monitor        10                2
Laptop_Case           20                0
Laptop_Bag            25                1 
Office_Chair          20                1 
Mouse                 10                0
Keyboard              10                0 

File_2
Item               Newly_order      Ref_Name  
Laptop_Monitor        15          HMX-190B-F  
Laptop_Bag            20          BMT-1920-U
Office_Chair          10          ORD-455_T

So From these the two files this is the output that I wish to have: 

outfile_1
Item            Availability   Broken    Newly_order     Total_Stock  
Laptop_Monitor       10           2         15             (10-2+15)
Laptop_Bag           25           1         20             (25-1+20)
Office_Chair         20           1         10             (20-1+10)

Can someone show me some head-ups on how to generate an output like this? I am new to Perl and this is the first assignment that I get.
