Solve the Subtraction Problem: 8651 minus 7740

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

• Step 1: Align the numbers by place value.

• Step 2: Subtract each digit starting from the rightmost side.

• Step 3: Perform borrowing where necessary.

Now, let's go through each step:
Step 1: Align the numbers:
$\begin{array}{c} 8651 \\ -7740 ~~~\\ \hline \end{array}$

Step 2: Begin with the unit place.
From the rightmost digit (units), subtract: $1 - 0 = 1$.

Step 3: Move to the tens place. Subtract $5 - 4 = 1$.

Step 4: Move to the hundreds place. Subtract $6 - 7$. Since 6 is less than 7, we borrow 1 from the thousands place:
Change 8 (thousands) to 7, and 6 becomes 16.
Now, subtract $16 - 7 = 9$.

Step 5: For the thousands place, after borrowing, subtract $7 - 7 = 0$.

Putting it all together, the result of the subtraction is $911$.

Therefore, the solution to the problem is $911$.
