(iii) Borrow 1 thousand leaving 5 thousands

1 thousand 2 hundred = 12 hundreds

12 hundreds – 7 hundreds = 5 hundreds

(iv) 5 thousands – 2 thousands = 3 thousands

Thus, 6351 – 2765 = 3586

SUBTRACTION FROM A NUMBER WITH ZEROES

Example: Subtract 3823 from 5600.

Solution: (i) We can not subtract 3 ones from 0 ones. Th H T O

We cannot borrow item from 0 ten. 15 9 10
4 5 10
So we borrow/hundred leaving 5 hundred.
5 6 0 0
1 hundred = 10 tens
– 3 8 2 3

Borrow 1 ten leaving 9 tens 7 7 7

1 ten = 10 ones

(ii) 10 ones – 3 ones = 7 ones
(iii) 9 tens – 2 tens = 7 tens

(iv) Borrow 1 thousand leaving 4 thousands

1 thousand 5 hundreds = 15 hundreds

15 hundreds - 8 hundreds = 7 hundreds

(iv) 4 thousands – 3 thousands = 1 thousands

Example: Subtract 6432 from 9000.

Solution: (i) We cannot borrow 1 ten from 0 ten or 1 hundred from 0

hundred.
We borrow 1 thousand leaving 8 thousands. Th H T O

1 thousand = 10 hundreds 9 9 10

Borrow 1 hundred leaving 9 hundreds 8 10 10

1 hundred = 10 tens 9 0 0 0
