Solve the Subtraction Problem: 8900 minus 490

To solve this problem, we will proceed with the following steps:

• Step 1: Align the Numbers
  We write the numbers 8900 and 490 aligning their digits by place value.
• Step 2: Begin Subtraction from the Rightmost Digit
  We will subtract each digit starting from the units place (rightmost). The operation will be column by column as follows:
• Units place: Since there's a zero in 8900 and zero in the units place of 490, we directly have zero. So, $0 - 0 = 0$.
• Tens place: There's a zero in the tens place of 8900 and 9 in 490. Here, borrow 1 from the hundreds place reducing it by 1 and converting tens digit to 10. Thus, $10 - 9 = 1$.
• Hundreds place: After borrowing, the hundreds digit in 8900 is reduced from 9 to 8. Thus, $8 - 4 = 4$.
• Thousands place: Finally, the thousands digit remains unchanged, hence $8 - 0 = 8$.
• Step 3: Verify Calculation
  Double-check each subtraction step to avoid errors.

Putting it all together, the subtraction result is $8410$.

Therefore, the solution to the equation $8900 - 490 = 8410$ and the correct answer is choice 3: $8410$.
