4 x 4 matrix array sum problem

dear all thank you for reading my thread.

I have a 4 x 4 matrix with the 5th column being the total for each row as follows:

1 2 3 4 10
5 6 7 8 26
9 10 11 12 42
13 14 15 16 58

I have an array formula to check to see if the total for each row column 1 to 4 equals the total 5th cloumn as follows:

{SUM(IF(E14:E17+F14:F17+G14:G17+H14:H17=I14:I17,1,0))} with the result being 4.

How do I use an array formula to test the matrix so for example sum(E14:h17) on a row level = I14:I17

Thanks and regards John

Or you can use conditional formatting on I column to paint values if not true:

=I4<>SUM(E4:H4)
