Add a row with a formula?

yuvalshmul

Hello,

In the flow attached, the first table has the input and the second has the (ideal) output

Basically, I need to add a row to the data that would substract the fourth row from the first row across all columns

Row 5 = Row 1 - Row 4

How could I do so?

Thank you so much!

@yuvalshmul 
This is my try.

I am wondering if it can be easy as in Excel 😁
