Spiegazione passo passo

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths	ten millionths	hundred millionths

	0	,	0	0	0	0	1
-	0	,	0	0	0	0	0	0	0	8
		,

Put zeros in the blank number places:

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths	ten millionths	hundred millionths

	0	,	0	0	0	0	1	0	0	0
-	0	,	0	0	0	0	0	0	0	8
		,

2. Subtract the numbers using long subtraction method

Because the upper digit (0) in the hundred millionths column is too small to get a positive difference, borrow 1 from the number to the left (100) which becomes (099) and get (10).

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths	ten millionths	hundred millionths
							0	9	9	10
	0	,	0	0	0	0	1	0	0	0
-	0	,	0	0	0	0	0	0	0	8
		,

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths	ten millionths	hundred millionths
							0	9	9	10

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

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths	ten millionths	hundred millionths
