Column traversal from right to left
Ones column:
  • Since 3 is less than 7, we have to borrow 1 from the Tens column
  • As a result, 3 becomes 13, and 13 − 7 = 6
  • The 0 in the Tens column becomes 9 after borrowing 1 from its regrouped value of 10

Tens column:

  • 9 − 7 = 2
  • Because it was the first nonzero digit to the left of the 3 in the Ones column, the 2 in the Hundreds column became 1 after 1 was borrowed for the purpose of regrouping the 0 in the Tens column (borrowing across a 0)

Hundreds column:

  • 1 − 0 = 1
