Grade 4 - Mathematics
1.18 Subtraction with Regrouping

Method:
  1. Start subtracting from the ones place.
  2. If the subtrahend is lesser than minuend in ones place then we borrow 1 from tens place.
  3. If the subtrahend is lesser than minuend in tens place then we borrow 1 from hundreds place

Example:
Subtraction with regrouping:

  1. Start from the ones place, 4 is lesser than 6. So 1 is borrowed from 2 and 4 becomes 14.
  2. In tens place, 2 becomes 1, now again 1 is less than 5, so 1 is borrowed from 8 and 1 becomes 11.
  3. In ones place 4 is subtracted from 7.
Answer: 368
Subtracting across zeros:

  1. When there is a zero it is always made 10 by borrrowing 1 from digits in higher place values.
  2. In ones place 4 is made 14 and zero is made 9 (since 1 is borrowed from 10 to make 14)
  3. In hundreds place 3 becomes 2.
Answer: 117
Directions: Subtract the following numbers. Also write at least ten examples of your own.
