Spiegazione passo passo

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

Place value	thousands	hundreds	tens	ones

	3	7	1	8
				8
-			8	7

2. Subtract the numbers using long subtraction method

Because the upper digit (8) 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 (18).

Place value	thousands	hundreds	tens	ones
			0	18
	3	7	1	8
				8
-			8	7

Subtract the numbers in the ones column from the top number:
18-8-7=3

Place value	thousands	hundreds	tens	ones
			0	18
	3	7	1	8
				8
-			8	7
				3

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	18
	3	7	1	8
				8
-			8	7
				3

Subtract the numbers in the tens column from the top number:
10-8=2

Place value	thousands	hundreds	tens	ones
		6	10
			0	18
	3	7	1	8
				8
-			8	7
			2	3

Write 6 in the hundreds place.

Place value	thousands	hundreds	tens	ones
		6	10
			0	18
	3	7	1	8
				8
-			8	7
		6	2	3

Write 3 in the thousands place.

Place value	thousands	hundreds	tens	ones
		6	10
			0	18
	3	7	1	8
				8
-			8	7
	3	6	2	3

The solution is: 3,623
