Spiegazione passo passo

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

Place value	ten thousands	thousands	hundreds	tens	ones

	1	0	1	0	5
			1	6	0
-			6	5	6

2. Subtract the numbers using long subtraction method

Because the upper digit (5) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (15).

Place value	ten thousands	thousands	hundreds	tens	ones
			0	9	15
	1	0	1	0	5
			1	6	0
-			6	5	6

Subtract the numbers in the ones column from the top number:
15-0-6=9

Place value	ten thousands	thousands	hundreds	tens	ones
			0	9	15
	1	0	1	0	5
			1	6	0
-			6	5	6
					9

Because the upper digit (9) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (100) which becomes (099) and get (19).

Place value	ten thousands	thousands	hundreds	tens	ones
	0	9	9	19
			0	9	15
	1	0	1	0	5
			1	6	0
-			6	5	6
					9

Subtract the numbers in the tens column from the top number:
19-6-5=8

Place value	ten thousands	thousands	hundreds	tens	ones
	0	9	9	19
			0	9	15
	1	0	1	0	5
			1	6	0
-			6	5	6
				8	9

Subtract the numbers in the hundreds column from the top number:
9-1-6=2

Place value	ten thousands	thousands	hundreds	tens	ones
	0	9	9	19
			0	9	15
	1	0	1	0	5
			1	6	0
-			6	5	6
			2	8	9

Write 9 in the thousands place.

Place value	ten thousands	thousands	hundreds	tens	ones
	0	9	9	19
			0	9	15
	1	0	1	0	5
			1	6	0
-			6	5	6
		9	2	8	9

Write 0 in the ten thousands place.

Place value	ten thousands	thousands	hundreds	tens	ones
	0	9	9	19
			0	9	15
	1	0	1	0	5
			1	6	0
-			6	5	6
	0	9	2	8	9

The solution is: 9,289
