The numbers subtraction to perform:
- 57 + 40 = ?

Rewrite the initial operation:

- 57 + 40 =

40 - 57

Subtract the numbers:
40 - 57 = ?

The second number is larger than the first.

The answer will be negative (less than zero).

To subtract the numbers just reverse them:

57 - 40 = ?

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.


 57
- 40
?

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

Subtract the digits in the ones column:

7 - 0 = 7.
7 is the ones digit.
Write it down at the base of the ones column.

- 40
  7

Subtract the digits in the tens column:

5 - 4 = 1.
1 is the tens digit.
Write it down at the base of the tens column.


 57
- 40
 17

The answer will be negative (less than zero):

40 - 57 = - 17

Final answer:
- 57 + 40 = - 17

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
