Spiegazione passo passo

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths

	1	,	0	0	2	6
-	0	,	0	5	8
		,

Put zeros in the blank number places:

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths

	1	,	0	0	2	6
-	0	,	0	5	8	0
		,

2. Subtract the numbers using long subtraction method

Subtract the numbers in the ten thousandths column from the top number:
6-0=6

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths

	1	,	0	0	2	6
-	0	,	0	5	8	0
		,				6

Because the upper digit (2) in the thousandths column is too small to get a positive difference, borrow 1 from the number to the left (1.00) which becomes (0.99) and get (12).

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
	0		9	9	12
	1	,	0	0	2	6
-	0	,	0	5	8	0
		,				6

Subtract the numbers in the thousandths column from the top number:
12-8=4

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
	0		9	9	12
	1	,	0	0	2	6
-	0	,	0	5	8	0
		,			4	6

Subtract the numbers in the hundredths column from the top number:
9-5=4

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
	0		9	9	12
	1	,	0	0	2	6
-	0	,	0	5	8	0
		,		4	4	6

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
	0		9	9	12
	1	,	0	0	2	6
-	0	,	0	5	8	0
		,	9	4	4	6

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths
	0		9	9	12
	1	,	0	0	2	6
-	0	,	0	5	8	0
	0	,	9	4	4	6

The solution is: 0,9446
