Addition result:

6,282 + 6,809 + 7,170,806 + 87 = 7,183,984

Answer:
- 6,282 - 6,809 - 7,170,806 - 87 = - 7,183,984

The initial operation has become:

71,783 - 6,282 - 6,809 + 67,939 - 7,170,806 - 87 =


139,722 - 7,183,984

Now subtract the final numbers above:
139,722 - 7,183,984 = ?

The second number is larger than the first.

The answer will be negative (less than zero).


To subtract the numbers just reverse them:

7,183,984 - 139,722 = ?


But at the end attach a minus sign in front of the result.


Method used below: column subtracting, from right to left (traditional)


Stack the numbers on top of each other.

The ones digits line up in the first column from the right.

The tens digits line up in the next column to the left.

Subtract the digits in the thousands column:

3 - 9 = ?

The second digit is larger than the first.
Borrow from the next column to the left.

The borrowing is a two step process:


Subtract 1 from the top digit in the column of the ten thousands: 8 - 1 = 7.
Cross out the top digit you've borrowed 1 from: 8.
Write the answer above that digit: 7.


When borrowing, 1 ten thousand = 10 thousands.
Add 10 to the top digit in the column of the thousands: 10 + 3 = 13.

     262

After borrowing, the subtraction has become:
13 - 9 = 10 + 3 - 9 = 10 + 3 - 9 = 3 + (10 - 9) = 3 + 1 = 4.
4 is the thousands digit.
Write it down at the base of the thousands column.
