Addition result:

493 + 148 + 243 + 172 = 1,056

Final answer:
- 493 - 148 - 243 - 172 = - 1,056

The initial operation has become:

- 493 - 148 - 243 - 172 + 216 + 171 + 248 =


635 - 1,056

Now subtract the final numbers above:
635 - 1,056 = ?

The second number is larger than the first.

The answer will be negative (less than zero).


To subtract the numbers just reverse them:

1,056 - 635 = ?


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 with the column on the right

Subtract the digits in the ones column:

6 - 5 = 1.
1 is the ones digit.
Write it down at the base of the ones column.

Subtract the digits in the hundreds column:

0 - 6 = ?

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 thousands: 1 - 1 = 0.
Cross out the top digit you've borrowed 1 from: 1.
Write the answer above that digit: 0.


When borrowing, 1 thousand = 10 hundreds.
Add 10 to the top digit in the column of the hundreds: 10 + 0 = 10.

Subtract the digits in the thousands column:

There is a single digit in this column: 1 0.
0 is the thousands digit.
Write it down at the base of the thousands column.

 0421

Leading zeros

When leading zeros occupy the most significant digits of a natural number, they could be left blank and the numeric value stays the same:

0421 = 421

The answer will be negative (less than zero):

635 - 1,056 = - 421

Final answer:
- 493 - 148 - 243 - 172 + 216 + 171 + 248 = - 421

How to subtract numbers? Let's learn with an example

The operation to perform: 52 - 37

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.
    •  52
      - 37

      ?
  • Subtract column by column; start with the column on the right.
  • Subtract the digits in the ones column: 2 - 7 = ?
    • The second digit is larger than the first. We need to borrow from the next column to the left:
      • Subtract 1 from the top digit in the column of the tens: 5 - 1 = 4.
      • Cross out the top digit you've borrowed 1 from: 5.
      • Write the answer above that digit: 4.
      • When borrowing, 1 ten = 10 ones: add 10 to the top digit in the column of the ones: 10 + 2 = 12.
    •  4 
       512
      - 37

         
    • After borrowing, the subtraction has become: 12 - 7 = 5.
    • 5 is the ones digit - write it down at the base of the ones column:
      •  4 
         512
        - 37

          5
  • Subtract the digits in the tens column:
    • 5 4 - 3 = 1.
    • 1 is the tens digit - write it down at the base of the tens column.
    •  4 
       512
      - 37

       15
  • Final answer: 52 - 37 = 15
