Calculate the Sum: 957 + 43 in Vertical Format

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

• Step 1: Align the Numbers

We will align the numbers by their place values:

$\begin{aligned} &957 \\ +& \\ &~~43 \\ \end{aligned}$

• Step 2: Perform Addition from Right to Left
• Units Place (rightmost column):

Add the digits in the ones place: $7 + 3 = 10$.
Since 10 is greater than 9, write down 0 in the ones place and carry over 1 to the tens place.

• Tens Place (middle column):

Add the digits in the tens place, including the carry-over: $5 + 4 + 1 = 10$.
Again, write down 0 in the tens place and carry over 1 to the hundreds place.

• Hundreds Place (leftmost column):

Add the digits in the hundreds place, including the carry-over: $9 + 1 = 10$.
Write down the entire 10 since there is no further place to carry over.

• Step 3: Write Down the Final Answer

The result of the addition is 1000.

Therefore, the solution to the problem is $1000$.
