$[\begin{array}{c} 0 & 1 & 2 \\ 1 & 1 & 0 \\ 1 & 1 & 0 \end{array}]$

चरण 1

Choose the row or column with the most

0

$0$ elements. If there are no

0

$0$ elements choose any row or column. Multiply every element in column

3

$3$ by its cofactor and add.

चरण 1.1

Consider the corresponding sign chart.

| \begin{array}{c} + & - & + \\ - & + & - \\ + & - & + \end{array} |

$| \begin{array}{c} + & - & + \\ - & + & - \\ + & - & + \end{array} |$

The cofactor is the minor with the sign changed if the indices match a

-

$-$ position on the sign chart.
