Step-by-Step Solution

To approach this problem, we'll use vertical addition of the numbers 12 and 8:

Step 1: Write the numbers vertically, aligning their place values.
$\begin{aligned} &12 \\ +& \\ &~~8 \\ \hline &~~? \\ \end{aligned}$
Step 2: Start adding from the rightmost column (units position).
Add the units: $2 + 8 = 10$ .
Write down the 0 in the units column and carry over the 1 to the tens column.
Step 3: Move to the next column on the left (tens position).
Add the tens: $1 + 1 = 2$ (including the carryover 1).
Write down the result in the tens column.
Step 4: Combine these results to find the final sum:
$\begin{aligned} &12 \\ +& \\ &~~8 \\ \hline &20 \\ \end{aligned}$

Therefore, the solution to the problem is $20$ .
