Exercise 4.1

1. Subtract the given numbers.

(a) 302 from 5,964 (b) 254 from 2,589 (c) 540 from 9,783
(d) 4,805 from 6,836 (e) 3,251 from 4,666 (f) 5,772 from 7,894

(g) 2,481 from 6,984 (h) 3,605 from 5,787 (i) 6,302 from 9,815

2. Find the following diff erences.

(a) 2,456 – 342 (b) 3,687 – 256 (c) 4,971 – 1,650

(d) 6,886 – 3,243 (e) 6,528 – 5,304 (f) 7,953 – 5,621
Subtraction of Numbers (with borrowing)

Example 2: Subtract 3,252 from 7,439. Th H T O

Solu on: Step 1: Subtract the ones. 7 4 3 9
9 – 2 = 7
– 3 2 5 2
Step 2: Subtract the tens.
7
5 being greater than 3 cannot be subtracted.
Thus, borrow 1 hundred from the

hundreds column and change 4 hundreds Th H T O
to 3 hundreds in the minuend. 3 13
7 4 3 9
Add the borrowed 1 hundred to 3 tens.
– 3 2 5 2
(1 hundred = 10 tens)
10 tens + 3 tens = 13 tens 8 7
Now, subtract 5 from 13.

13 – 5 = 8
Th H T O
Write 8 under the tens place. 3 13
7 4 3 9
Step 3: Subtract the remaining hundreds.
3 – 2 = 1 – 3 2 5 2

Write 1 under the hundreds place. 1 8 7

Step 4: Subtract the thousands and write the Th H T O
diff erence under the thousands place. 3 13
7 4 3 9
7 – 3 = 4
So, 7,439 – 3,252 = 4,187. – 3 2 5 2
4 1 8 7
