Example with Solution

Example

384
-138
246

Answer:

246

Solution Steps

  1. 1 Write numbers 384 and 138 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: 4 is less than 8. Borrow 1 from the next column. 4 + 10 = 14.
  4. 4 In ones place: 14 - 8 = 6.
  5. 5 In tens place: 7 - 3 = 4.
  6. 6 In hundreds place: 3 - 1 = 2.
  7. 7 Result: 384 - 138 = 246
