Adding Multiple Identical tables to a Master Identical table

Hello!
It seems like a easy task but I have not been able to figure it out.
I have 4 identical tables. 1 I would like to be the Master table that adds all the data from the other 3.
I know how to put formulas in each cell of the master table to accomplish this but what I would like to know if there an way to add the tables instead of adding the cells. It would be must faster to do it this way.


This is how I would like it to work:

Attach a sample workbook. Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.
