1 thousand and 3 hundreds – 8 hundreds

= 10 hundreds and 3 hundreds – 8 hundreds

= 13 hundreds – 8 hundreds = 5 hundreds.

Example 2: Subtract 3705 from 7132. Th H T O

Solution: Step 1: 5 ones cannot be subtracted 2 12
from 2 ones, so we borrow 1 7 1 3 2
ten from 3 tens. We cross out
– 3 7 0 5
3 and write 2. Also we cross
out 2 and write 12. 7

12 ones – 5 ones = 7 ones. Th H T O
2 12
We write 7 in ones column.

Step 2: 2 tens – 0 tens = 2 tens. 7 1 3 2

We write 2 in tens column. – 3 7 0 5
2 7

Step 3: 7 hundreds cannot be subtracted from 1 hundred,
so we borrow 1 thousand from 7 thousands, we
cross out 7 and write 6.
Th H T O
Also we cross out 1 and write
6 11 2 12
11.
7 1 3 2
11 hundreds – 7 hundreds = 4
hundreds. – 3 7 0 5

We write 4 in hundreds 4 2 7
column.

Step 4: 6 thousands – 3 thousands Th H T O
6 11 2 12
= 3 thousands.

We write 3 in thousands column. 7 1 3 2

Ans. 3427 – 3 7 0 5
