Spiegazione passo passo

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

Place value	thousands	hundreds	tens	ones

	2	7	1	6
-		8	3	9

2. Subtract the numbers using long subtraction method

Because the upper digit (6) in the ones column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (16).

Place value	thousands	hundreds	tens	ones
			0	16
	2	7	1	6
-		8	3	9

Subtract the numbers in the ones column from the top number:
16-9=7

Place value	thousands	hundreds	tens	ones
			0	16
	2	7	1	6
-		8	3	9
				7

Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the digit (7) in the next number place which becomes (6) and get (10).

Place value	thousands	hundreds	tens	ones
		6	10
			0	16
	2	7	1	6
-		8	3	9
				7

Subtract the numbers in the tens column from the top number:
10-3=7

Place value	thousands	hundreds	tens	ones
		6	10
			0	16
	2	7	1	6
-		8	3	9
			7	7

Because the upper digit (6) in the hundreds 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 (16).

Place value	thousands	hundreds	tens	ones
	1	16
		6	10
			0	16
	2	7	1	6
-		8	3	9
			7	7

Subtract the numbers in the hundreds column from the top number:
16-8=8

Place value	thousands	hundreds	tens	ones
	1	16
		6	10
			0	16
	2	7	1	6
-		8	3	9
		8	7	7

Write 1 in the thousands place.

Place value	thousands	hundreds	tens	ones
	1	16
		6	10
			0	16
	2	7	1	6
-		8	3	9
	1	8	7	7

The solution is: 1,877
