Subtract 1506 from 6315: Vertical Format Solution

$\begin{aligned} &6315 \\ -& \\ &1506 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

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

• Step 1: Align the numbers by place value.
• Step 2: Subtract each corresponding digit from right to left.
• Step 3: Borrow from the left if the top digit is smaller than the bottom digit.

Now, let's work through each step:

Step 1: Align 6315 and 1506 vertically by place values:
$\begin{aligned} &6315 \\ -&1506 \\ \hline & \end{aligned}$

Step 2: Start subtracting from the units place:

Units place: $5 - 6$. Since 5 is smaller than 6, we need to borrow 1 from the tens place.
1 becomes 0 (in the tens place), and 5 becomes 15:
$15 - 6 = 9$.

Tens place: Now it’s $0 - 0$. That gives us $0$.

Hundreds place: $3 - 5$ in the hundreds place. Since 3 is smaller than 5, we borrow 1 from the thousands place.
3 becomes 13 and 6 becomes 5:
$13 - 5 = 8$.

Thousands place: $5 - 1 = 4$.

Therefore, the result of subtraction is $4809$.

According to the provided answer choices, the correct choice is choice 3, which is the number $4809$.

The solution to the problem is $4809$.
