Place value	tens	ones	.	tenths	hundredths	thousandths

	1	0	,	1	2	1

Because the upper digit (1) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (11).

Place value	tens	ones	.	tenths	hundredths	thousandths

Subtract the numbers in the thousandths column from the top number:
11-6=5

Place value	tens	ones	.	tenths	hundredths	thousandths

			,			5

Because the upper digit (1) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (11).

Subtract the numbers in the hundredths column from the top number:
11-6=5

Subtract the numbers in the tenths column from the top number:
0-0=0

Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (10).

Place value	tens	ones	.	tenths	hundredths	thousandths
	0	10
				0	11
					1	11
	1	0	,	1	2	1
-		5	,	0	6	6
			,	0	5	5

Subtract the numbers in the ones column from the top number:
10-5=5

Place value	tens	ones	.	tenths	hundredths	thousandths
	0	10
				0	11
					1	11
	1	0	,	1	2	1
-		5	,	0	6	6
		5	,	0	5	5

Write 0 in the tens place.
