Solution Steps

00:00 Solve

00:03 Each time it's considered a shortage of 2 digits, and then we place

00:07 1 is less than 2

00:12 Therefore we subtract 1 from the tens and add this amount to the ones

00:15 Meaning now instead of 1 we will have 11

00:19 We subtract the ones from the ones plus the ten

00:22 We place in the ones

00:25 2 is less than 5

00:29 Therefore we subtract 1 from the hundreds and add this amount to the tens

00:34 Meaning now instead of 2 we will have 12

00:40 We subtract the tens from the tens plus the ten

00:44 We place in the tens

00:47 We subtract hundreds from hundreds, and place in hundreds

00:52 We subtract thousands from thousands, and place in thousands

00:56 And this is the solution to the question

Step-by-Step Solution

The solution involves the vertical subtraction of $8731 - 3252$ . Let's break it down step-by-step:

Step 1: Align the numbers at the units column for vertical subtraction:
$\begin{array}{c} &8 & 7 & 3 & 1 \\ - & 3 & 2 & 5 & 2 \\ \hline \end{array}$
Step 2: Subtract the units place: $1 - 2$ . Since $1$ is smaller than $2$ , we need to borrow from the tens.
Borrowing from $3$ (tens), which becomes $2$ , and the units position turns from $1$ to $11$ . Now subtract: $11 - 2 = 9$ .
Step 3: Move to the tens place: $2 - 5$ . Again, $2$ is smaller than $5$ , borrow from the hundreds.
Borrow from $7$ (hundreds), which becomes $6$ , and the tens becomes $12$ . Now subtract: $12 - 5 = 7$ .
Step 4: Move to the hundreds place: $6 - 2$ . This results in $4$ .
Step 5: Finally, move to the thousands place: $8 - 3$ . This results in $5$ .
Scale down the entire calculation:
$5479$

Therefore, the result of $8731 - 3252$ is $\textbf{5479}$ .

This corresponds to choice 4:
