Solve: Finding the Difference Between 514941 and 221871

To solve this subtraction problem, follow these steps:

• Step 1: Write down the numbers in vertically aligned format, placing the bigger number (514941) on top and the smaller number (221871) underneath it, ensuring digits are aligned according to their place value.

• Step 2: Begin with the rightmost digits. Subtract the units place: $1 - 1 = 0$.

• Step 3: Move to the tens place. Subtract: $4 - 7$. Since 4 is less than 7, we need to borrow 1 from the next left column (hundreds place). The 9 becomes 8, and the 4 becomes 14. Now, subtract: $14 - 7 = 7$.

• Step 4: Hundreds place. Subtract $8 - 8 = 0$.

• Step 5: Thousands place. Subtract $4 - 1 = 3$.

• Step 6: Ten-thousands place. Subtract $1 - 2$. Borrow 1 from the hundred-thousands place, which makes 5 become 4. Now, $11 - 2 = 9$.

• Step 7: Hundred-thousands place. Subtract $4 - 2 = 2$.

Upon performing these steps, the calculated difference of the two numbers is:

The answer is $\boldsymbol{293070}$.

Therefore, the solution to the subtraction is $293070$, which matches choice 4.
