Answer 5

Actually, the matrix is

8 7 4
2 0 5

and it has 2 rows and 3 columns.

In\[m _{12}\] typing m12, you actually meant \[m _{12}\]

Answer 6

I know, I just could not find out how to put it all like that. thank you for clarifying. I really need help understanding this.

Answer 7

where that 12 is a subscript. The subscript says "first row, second column."

Look at your matrix again. where's the first row? Where's the 2nd column? Which element has the first-row-second-column position?
