Solution Steps

00:00 Solve
00:03 Each time we calculate the sum of 2 digits, and then we substitute
00:06 Let's start by adding ones with ones
00:09 Place the ones, and remember 1 above
00:12 Add tens with tens, remember to add 1 to the calculation
00:19 Place in the tens position
00:23 And this is the solution to the question

Step-by-Step Solution

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

  • Step 1: Align the numbers 52 and 39 for vertical addition.
  • Step 2: Add the ones place digits: 2 + 9.
  • Step 3: Handle any carry if needed and proceed to the tens place: 5 + 3.

Let's work through each step:

Step 1: Write the numbers in vertical alignment:

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

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

2+9=11 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 5 + 3 + 1 = 9 .

Write 9 in the tens place.

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

Thus, the correct solution to the problem is 91.
