Adding whole numbers horizontally and vertically by regrouping

2 549 384 + 6 986 768 =

Solution

Use the following steps for horizontal addition:

1. Add ones: 4 + 8 = 12. Write 2 in the ones place. Regroup 10 ones into 1 tens and add it to the tens place.
2. Add tens: 1 + 8 + 6 = 15. Write 5 in the tens place. Regroup 10 tens into 1 hundreds and add it to the hundreds place.
3. Add hundreds: 1 + 3 + 7 = 11. Write 1 in the hundreds place. Regroup 10 hundreds into 1 thousands and add it to the thousands place.
4. Add thousands: 1 + 9 + 6 = 16. Write 6 in the thousands place. Regroup 10 thousands into 1 ten thousands and add it to the ten thousands place.
5. Add ten thousands: 1 + 4 + 8 = 13. Write 3 in the ten thousands place. Regroup 10 ten thousands into 1 hundred thousands and add it to the hundred thousands place.
6. Add hundred thousands: 1 + 5 + 9 = 15. Write 5 in the hundred thousands place. Regroup 10 hundred thousands into 1 millions and add it to the millions place.
7. Add millions: 1 + 2 + 6 = 9. Write 9 in the millions place.

2 549 384 + 6 986 768 = _ _ _ _ _ _ 2

2 549 384 + 6 986 768 = _ _ _ _ 1 5 2

2 549 384 + 6 986 768 = _ _ _ _ _ 5 2

2 549 384 + 6 986 768 = _ _ _ 6 1 5 2

2 549 384 + 6 986 768 = _ _ 3 6 1 5 2

2 549 384 + 6 986 768 = _ 5 3 6 1 5 2

Therefore, 2 549 384 + 6 986 768 = 9 536 152.
