[\begin{matrix} - 18 & 6 - 18 & 4 \end{matrix}] - [\begin{matrix} - 16 & - 12 0 & - 18 \end{matrix}]

$[\begin{array}{c} - 18 & 6 \\ - 18 & 4 \end{array}] - [\begin{array}{c} - 16 & - 12 \\ 0 & - 18 \end{array}]$

Step 1

Subtract the corresponding elements.

[\begin{matrix} - 18 + 16 & 6 + 12 - 18 - 0 & 4 + 18 \end{matrix}]

$[\begin{array}{c} - 18 + 16 & 6 + 12 \\ - 18 - 0 & 4 + 18 \end{array}]$

Step 2

Step 2.1

Add

- 18

$- 18$ and

16

$16$ .

[\begin{matrix} - 2 & 6 + 12 - 18 - 0 & 4 + 18 \end{matrix}]

$[\begin{array}{c} - 2 & 6 + 12 \\ - 18 - 0 & 4 + 18 \end{array}]$

Step 2.2

Add

6

$6$ and

12

$12$ .

[\begin{matrix} - 2 & 18 - 18 - 0 & 4 + 18 \end{matrix}]

$[\begin{array}{c} - 2 & 18 \\ - 18 - 0 & 4 + 18 \end{array}]$

Step 2.3

Subtract

0

$0$ from

- 18

$- 18$ .

[\begin{matrix} - 2 & 18 - 18 & 4 + 18 \end{matrix}]

$[\begin{array}{c} - 2 & 18 \\ - 18 & 4 + 18 \end{array}]$

Step 2.4

Add

4

$4$ and

18

$18$ .

[\begin{matrix} - 2 & 18 - 18 & 22 \end{matrix}]

$[\begin{array}{c} - 2 & 18 \\ - 18 & 22 \end{array}]$

[\begin{matrix} - 2 & 18 - 18 & 22 \end{matrix}]

$[\begin{array}{c} - 2 & 18 \\ - 18 & 22 \end{array}]$
