Solve Two-Digit Addition: 52 + 39 in Vertical Format

Video Solution

Solution Steps

00:05 Let's solve the problem together.

00:08 We're going to add two digits, and remember our result.

00:12 First, add the ones digits together.

00:16 Place the sum in the ones column, and carry over one if needed.

00:20 Now, add the tens digits. Don't forget to include the one you carried over.

00:25 Put that result in the tens place.

00:29 And there you have it, the problem is solved!

Step-by-Step Solution

To solve this problem, we'll follow these steps:

Let's work through each step:

Step 1: Write the numbers in vertical alignment:

$\begin{array}{c} 52 \\ +39 \\\hline \end{array}$

Step 2: Add the digits in the ones column (rightmost):

$2 + 9 = 11$ . Since this is more than 9, write 1 in the ones place and carry over 1 to the tens place.

Step 3: Add the digits in the tens place:

Including the carried over 1 from the ones addition, add $5 + 3 + 1 = 9$ .

Write 9 in the tens place.

Therefore, the sum of $52 + 39$ is $91$ .

Thus, the correct solution to the problem is 91.
