Solve Vertical Subtraction: 7189 minus 2392

$\begin{aligned} &7189 \\ -& \\ &2392 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we'll use the vertical subtraction method, breaking down the problem into each column from right to left:

• Step 1: Start with the rightmost column (units).
• Units: $9 - 2 = 7$.
• Step 2: Move to the tens column.
• Tens: As $8 - 9$ is not possible, regroup by borrowing 1 from the hundreds column, making it $18 - 9 = 9$.
• Step 3: Proceed to the hundreds column.
• After borrowing, the hundreds column has $0 - 3$ (as it was reduced from 1), borrow from the thousands column: $10 - 3 = 7$.
• Step 4: Finally, calculate the thousands column.
• After borrowing from the thousands, it is now $6 - 2 = 4$.

Putting it all together, we find that:

$7189 - 2392 = 4797$.

The correct answer is $4797$.
