Solution Steps

00:00 Solve

00:03 Each time consider a shortage of 2 digits, and then we'll place

00:06 5 is less than 6

00:09 Therefore, we subtract 1 from the tens and add this amount to the ones

00:13 Meaning now instead of 5 we'll have 15

00:17 Subtract the ones from the ones plus ten

00:21 Place in ones

00:25 0 is less than 4

00:28 Therefore, we subtract 1 from the hundreds and add this amount to the tens

00:35 Meaning now instead of 0 we'll have 10

00:40 Subtract the tens from the tens plus ten

00:43 Place in tens

00:47 1 is less than 2

00:52 Therefore, we subtract 1 from the thousands and add this amount to the hundreds

00:57 Meaning now instead of 1 we'll have 11

01:03 Subtract the hundreds from the hundreds plus hundred

01:07 Place in hundreds

01:11 Subtract thousands from thousands, and place in thousands

01:14 And this is the solution to the question

Step-by-Step Solution

To solve the subtraction problem $7015 - 4246$ , we will proceed with vertical subtraction by following these steps:

Let's perform the subtraction:

Step 1: Align the numbers vertically:

$\begin{array}{cccc} & & & 7015 \\ - & & & 4246 \\ \hline \end{array}$

Step 2: Subtract from the rightmost digit (units place):

Units: $5 - 6$ is not possible without borrowing, so we borrow 1 from the tens place.
This makes the units place $15 - 6 = 9$ .

Step 3: Move to the tens place:

After borrowing, tens: $0$ becomes $10$ , and you initially borrowed $1$ , so you'll have $10 - 1 - 4 = 6$ .

Step 4: Move to the hundreds place:

The hundreds have already been adjusted for borrowing, it's originally $1$ (borrowed from thousands), so computing $9 - 2 = 7$ .

Step 5: Move to the thousands place:

Thus, the result of the subtraction $7015 - 4246$ is $2769$ .

Therefore, the correct answer choice, comparing against the given options, is 2769, corresponding to choice 2769.
