-5 3 0 4
2 3 1 2
6 7 3 0
1 5 3 0

A(3, 4) ?

The row #3 is:
6 7 3 0
The Column #4 on that row:
0

Then, A(3, 4) = 0

I assume that you're listing the elements by row: -5 3 0 4 is the first row, etc.

Then A(3,4) is the 4th element in the 3rd row, which is 0.

Row, column. When given a 3x2 it means 3rows by two columns.
Answer 0
(assuming you listed rows)
