LP 2 – Subtraction with borrowing (3-digit numbers)

Learning objective: The students will be able to perform subtraction of 3-

digit numbers with borrowing.

 Subtraction means taking away smaller number from a larger
number. Subtraction is signified by the ‘Minus’ (–) sign.

 Sometimes in subtraction we need a little bit extra in order to
do the operation, so we borrow a number from the column to
the left.
 In subtraction, we borrow when the subtrahend is greater than
the minuends.

Example: 246 – 158=?
Step 1: Write the numbers you wish to subtract, one underneath the
other in column wise. Now look at the numbers in the right-most

Step 2 : First we subtract the Ones column. Check if the

number at the bottom of the column:
