Spiegazione passo passo

1. Rewrite the numbers from top to bottom, aligned by their place values

Place value	ones	.	tenths	hundredths	thousandths

	9	,	8	5
-	0	,	2	8	2
		,

Put zeros in the blank number places:

Place value	ones	.	tenths	hundredths	thousandths

	9	,	8	5	0
-	0	,	2	8	2
		,

2. Subtract the numbers using long subtraction method

Because the upper digit (0) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (5) in the next number place which becomes (4) and get (10).

Place value	ones	.	tenths	hundredths	thousandths
				4	10
	9	,	8	5	0
-	0	,	2	8	2
		,

Subtract the numbers in the thousandths column from the top number:
10-0-2=8

Place value	ones	.	tenths	hundredths	thousandths
				4	10
	9	,	8	5	0
-	0	,	2	8	2
		,			8

Because the upper digit (4) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (14).

Place value	ones	.	tenths	hundredths	thousandths
			7	14
				4	10
	9	,	8	5	0
-	0	,	2	8	2
		,			8

Subtract the numbers in the hundredths column from the top number:
14-8=6

Place value	ones	.	tenths	hundredths	thousandths
			7	14
				4	10
	9	,	8	5	0
-	0	,	2	8	2
		,		6	8

Subtract the numbers in the tenths column from the top number:
7-2=5

Place value	ones	.	tenths	hundredths	thousandths
			7	14
				4	10
	9	,	8	5	0
-	0	,	2	8	2
		,	5	6	8

Subtract the numbers in the ones column from the top number:
9-0=9

Place value	ones	.	tenths	hundredths	thousandths
			7	14
				4	10
	9	,	8	5	0
-	0	,	2	8	2
	9	,	5	6	8

The solution is: 9,568
