Subtraction of whole numbers arranged vertically without regrouping

Subtraction of whole numbers arranged vertically without regrouping

Example

  675
− 123

  984
− 564

  234
− 012

Solution

The steps for vertical subtraction are the same as horizontal subtraction. Start to subtract from ones to hundred millions.

  6 7 5 9 8 4 2 3 4
−   1 2 3 5 6 4 0 1 2

  5 5 2 4 2 0 2 2 2

Therefore, the answer is 552,420,222.

Steps

Step	Description
1. Subtract ones: 0 – 1: It is not sufficient. Take 1 group of tens from 4 tens and regroup it to get 10 ones. Add ones: 10 + 0 = 10. Now, subtract ones: 10 − 1 = 9. Write 9 in the ones place. Remember, 1 tens was regrouped into 10 ones. Thus, 3 tens remained in the tens place.	867,352,140 − 295,771,671 = _ _ _ _ _ _ _ _ 9
2. Subtract tens: 3 – 7: It is not sufficient. Take 1 group of hundreds from 1 hundreds and regroup it to get 10 tens. Add tens: 10 + 3 = 13. Now, subtract tens: 13 – 7 = 6. Write 6 in the tens place. Remember 1 hundreds was regrouped into 10 tens. Thus, 0 hundreds remained in the hundreds place.	867,352,140 − 295,771,671 = _ _ _ _ _ _ _ 69
3. Subtract hundreds: 0 – 6: It is not sufficient. Take 1 group of thousands from 2 thousands and regroup it to get 10 hundreds. Add hundreds: 10 + 0 = 10. Now, subtract hundreds: 10 – 6 = 4. Write 4 in the hundreds place. Remember 1 thousands was regrouped into 10 hundreds. Thus, 1 thousands remained in the thousands place.	867,352,140 − 295,771,671 = _ _ _ _ _ _ 469
4. Subtract thousands: 1 – 1 = 0. Write 0 in the thousands place.	867,352,140 − 295,771,671 = _ _ _ _ _ 0469
5. Subtract ten thousands: 5 – 7: It is not sufficient. Take 1 group of hundred thousands from 3 hundred thousands and regroup it to get 10 ten thousands. Add ten thousands: 10 + 5 = 15. Now, subtract ten thousands: 15 – 7 = 8. Write 8 in the ten thousands place. Remember 1 hundred thousands was regrouped into 10 ten thousands. Thus, 2 hundred thousands remained in the hundred thousands place.	867,352,140 − 295,771,671 = _ _ _ _ 80,469
6. Subtract hundred thousands: 2 – 7: It is not sufficient. Take 1 group of millions from 7 millions and regroup it to get 10 hundred thousands. Add hundred thousands: 10 + 2 = 12. Now, subtract hundred thousands: 12 – 7 = 5. Write 5 in the hundred thousands place. Remember 1 millions was regrouped into 10 hundred thousands. Thus, 6 millions remained in the millions place.	867,352,140 − 295,771,671 = _ _ _ 580,469
7. Subtract millions: 6 – 5 = 1. Write 1 in the millions place.	867,352,140 − 295,771,671 = _ _ 1,580,469
8. Subtract ten millions: 6 – 9: It is not sufficient. Take 1 hundred millions from 8 hundred millions and regroup it into 10 ten millions. Add ten millions: 10 + 6 = 16. Now, subtract ten millions: 16 – 9 = 7. Write 7 in the ten millions place. Remember, 1 hundred millions was regrouped into 10 ten millions. Thus, 7 hundred millions remained in the hundred millions place.	867,352,140 − 295,771,671 = _ 71,580,469
9. Subtract hundred millions: 7 – 2 = 5. Write 5 in the hundred millions place.	867,352,140 − 295,771,671 = 571,580,469

Therefore, 867,352,140 – 295,771,671 = 571,580,469.
