Matrix

So in Algebra 2, we are learning about matrix's and how to solve them. One of the thing that you need to know when solving a matrix is to tell the difference between a column and a row. I was having trouble telling them apart. One of the tricks that Mrs. Denison told me was to think the columns look like a Roman column. That they go up and down and they hold up buildings. Ever since she told me that I haven't gotten confused since.
