Solve the equation:
8900−490=
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.
