Addition and Subtraction of 3-digit Numbers 71

Step 2: Now, check the tens digits. 4 < 6, so we borrow H T O

1 hundred from 6 hundreds. 5 14 14

10 tens + 4 tens = 14 tens (1 hundred = 10 tens) 6 5 4

After borrowing, change the hundreds digit – 3 6 8

from 6 to 5. 8 6

Now, subtract the tens digits. i.e. 14 – 6 = 8 tens

Write 8 in tens column.

Step 3: Subtract the hundreds digits. H T O

14 14
5
5 – 3 = 2 hundreds 6 5 4
Write 2 in hundreds column. – 3 6 8

Thus, 654 – 368 = 286 2 8 6

Subtract the following.

H T O H T O H T O H T O

4 2 6 5 0 2 4 8 7 5 3 8

– 8 7 – 3 5 – 6 8 – 3 4 6

H T O H T O H T O H T O

4 7 9 6 7 2 5 2 1 6 2 5
– 2 8 5 – 5 8 3 – 4 3 2 – 2 3 9
