Addition result:

508 + 1,977 = 2,485

Answer:
- 508 - 1,977 = - 2,485

The initial operation has become:

- 508 + 726 + 170 - 1,977 + 99 =


995 - 2,485

Now subtract the final numbers above:
995 - 2,485 = ?

The second number is larger than the first.

The answer will be negative (less than zero).


To subtract the numbers just reverse them:

2,485 - 995 = ?


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.

And so on...

Subtract column by column; start from the column on the right

Subtract the digits in the ones column:

5 - 5 = 0.
0 is the ones digit.
Write it down at the base of the ones column.

    0

Subtract the digits in the tens column:

8 - 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 hundreds: 4 - 1 = 3.
Cross out the top digit you've borrowed 1 from: 4.
Write the answer above that digit: 3.


When borrowing, 1 hundred = 10 tens.
Add 10 to the top digit in the column of the tens: 10 + 8 = 18.


  3

-  995

    0

After borrowing, the subtraction has become:
18 - 9 = 10 + 8 - 9 = 10 + 8 - 9 = 8 + (10 - 9) = 8 + 1 = 9.
9 is the tens digit.
Write it down at the base of the tens column.

   90

Subtract the digits in the hundreds column:

4 3 - 9 = ?

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

Subtract 1 from the top digit in the column of the thousands: 2 - 1 = 1.
Cross out the top digit you've borrowed 1 from: 2.
Write the answer above that digit: 1.


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


 113  
 24185
-  995

   90

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

Subtract the digits in the thousands column:

There is a single digit in this column: 2 1.
1 is the thousands digit.
Write it down at the base of the thousands column.


 113  
 24185
-  995

 1490

The answer will be negative (less than zero):

995 - 2,485 = - 1,490

Final answer:
- 508 + 726 + 170 - 1,977 + 99 = - 1,490
