Spiegazione passo passo

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

Place value	ones	.	tenths	hundredths	thousandths

	9	,	2	6	3
-	0	,	7	6	7
		,

2. Subtract the numbers using long subtraction method

Because the upper digit (3) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (13).

Place value	ones	.	tenths	hundredths	thousandths
				5	13
	9	,	2	6	3
-	0	,	7	6	7
		,

Subtract the numbers in the thousandths column from the top number:
13-7=6

Place value	ones	.	tenths	hundredths	thousandths
				5	13
	9	,	2	6	3
-	0	,	7	6	7
		,			6

Because the upper digit (5) in the hundredths 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 (15).

Place value	ones	.	tenths	hundredths	thousandths
			1	15
				5	13
	9	,	2	6	3
-	0	,	7	6	7
		,			6

Subtract the numbers in the hundredths column from the top number:
15-6=9

Place value	ones	.	tenths	hundredths	thousandths
			1	15
				5	13
	9	,	2	6	3
-	0	,	7	6	7
		,		9	6

Because the upper digit (1) in the tenths column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (11).

Place value	ones	.	tenths	hundredths	thousandths
	8		11
			1	15
				5	13
	9	,	2	6	3
-	0	,	7	6	7
		,		9	6

Subtract the numbers in the tenths column from the top number:
11-7=4

Place value	ones	.	tenths	hundredths	thousandths
	8		11
			1	15
				5	13
	9	,	2	6	3
-	0	,	7	6	7
		,	4	9	6

Subtract the numbers in the ones column from the top number:
8-0=8

Place value	ones	.	tenths	hundredths	thousandths
	8		11
			1	15
				5	13
	9	,	2	6	3
-	0	,	7	6	7
	8	,	4	9	6

The solution is: 8,496
