Have you ever noticed that the coordinates for row and column are in the reverse order of x and y coordinates?
I did not notice this until recently. Suppose you have a chart divided into rows and columns. We typically give the row first and then the column. If someone asks what is in position (2,5) we go up to the second row and then across to the fifth column. In the (x,y) system, we move 2 spaces horizontally for x and then 5 spaces up for y.
