Example with Solution

Example

746
-179
567

Answer:

567

Solution Steps

  1. 1 Write numbers 746 and 179 one below the other, aligning digits.
  2. 2 Start from the right side (ones place) and subtract digits in each column.
  3. 3 In ones place: 6 is less than 9. Borrow 1 from the next column. 6 + 10 = 16.
  4. 4 In ones place: 16 - 9 = 7.
  5. 5 In tens place: 3 is less than 7. Borrow 1 from the next column. 3 + 10 = 13.
  6. 6 In tens place: 13 - 7 = 6.
  7. 7 In hundreds place: 6 - 1 = 5.
  8. 8 Result: 746 - 179 = 567
