Subtract 2D array elements and insert the result into a new row

[Redney]

I need to subtract two consecutive elements of multiple rows in 2D array and assign them to a new row. Attached file the previous question.

Here is a simple representation of an example of how to subtract two consecutive values in a row and then add all the values to a new row. This sample only subtracts the same two values per row. If multiple subtractions per row are needed than another For Loop internally would be needed.
