Remember the word "arc" for ar,c or arc.

The "r" stands for the row, the "c" stands for the column.

The columns are vertical (from top to bottom) like the columns on a house 
or building.  The rows go horizontal (from left to right) 

So a1,2 or a12 means the element in row 1 (the top row)
and column 2 (the middle column), which is the 2.
