Step-by-Step Solution

To solve this problem, we will use vertical addition to find the sum of 52 and 9. Let's follow the steps outlined:

Step 1: Align the numbers.
Write the numbers so that the ones digits align vertically:

$\begin{array}{cc} & 5 & 2 \\ + & & 9 \\ \hline \end{array}$

Step 2: Add the ones digits.
First, add the digits in the far right column (ones place): $2 + 9 = 11$ .
Step 3: Handle the carry-over.
Since 11 is greater than 9, write the 1 in the ones place and carry over the 1 to the tens place:

$\text{Carry: } 1 \quad \quad$ $\begin{array}{cc} & 5 & 2 \\ + & & 9 \\ \hline & 6 & 1 \\ \end{array}$

Step 4: Add the tens digits, including any carry-over.
Next, add the digits in the tens place: $5 + 1 = 6$ .
Step 5: Write the final result.

Therefore, the sum of 52 and 9 is $61$ .

The correct answer is choice $3$ with the final total being $61$ .
