Step 2.1

Add $3$ and $2$ .

$[\begin{array}{c} 5 & \frac{1}{2} - \frac{5}{2} & 5 + 0 \\ 1 + 0 & - 1 + 2 & 3 - 3 \end{array}]$

Step 2.2

Combine the numerators over the common denominator.

$[\begin{array}{c} 5 & \frac{1 - 5}{2} & 5 + 0 \\ 1 + 0 & - 1 + 2 & 3 - 3 \end{array}]$

Step 2.3

Subtract $5$ from $1$ .

$[\begin{array}{c} 5 & \frac{- 4}{2} & 5 + 0 \\ 1 + 0 & - 1 + 2 & 3 - 3 \end{array}]$

Step 2.4

Divide $- 4$ by $2$ .

$[\begin{array}{c} 5 & - 2 & 5 + 0 \\ 1 + 0 & - 1 + 2 & 3 - 3 \end{array}]$

Step 2.5

Add $5$ and $0$ .

$[\begin{array}{c} 5 & - 2 & 5 \\ 1 + 0 & - 1 + 2 & 3 - 3 \end{array}]$

Step 2.6

Add $1$ and $0$ .

$[\begin{array}{c} 5 & - 2 & 5 \\ 1 & - 1 + 2 & 3 - 3 \end{array}]$

Step 2.7

Add $- 1$ and $2$ .

$[\begin{array}{c} 5 & - 2 & 5 \\ 1 & 1 & 3 - 3 \end{array}]$

Step 2.8

Subtract $3$ from $3$ .

$[\begin{array}{c} 5 & - 2 & 5 \\ 1 & 1 & 0 \end{array}]$
