Matrix are used to represent numbers in rows and columns.

The position of the matrix elements are:

  • \mathbf{7 \to a_{21}}
  • \mathbf{-5 \to a_{34}}
  • \mathbf{-1 \to a_{12} }

Matrix elements are named using the row and column, the element belongs to.

For instance:

The name of an element in the third row and fifth column of a matrix b is \mathbf{ b_{35}}

Using the above explanation, the name of 7, -5 and -1 is as follows;

7 belongs to row 2 and column 1

So, the name is: \mathbf{ a_{21}}

\mathbf{7 \to a_{21}}

-5 belongs to row 3 and column 4

So, the name is: \mathbf{ a_{34}}

\mathbf{-5 \to a_{34}}

-1 belongs to row 1 and column 2

So, the name is: \mathbf{ a_{12}}

\mathbf{-1 \to a_{12} }
