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.
