Spiegazione passo passo

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

Place value	thousands	hundreds	tens	ones

	7	4	7	3
-	2	8	7	5

2. Subtract the numbers using long subtraction method

Because the upper digit (3) in the ones 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 (13).

Place value	thousands	hundreds	tens	ones
			6	13
	7	4	7	3
-	2	8	7	5

Subtract the numbers in the ones column from the top number:
13-5=8

Place value	thousands	hundreds	tens	ones
			6	13
	7	4	7	3
-	2	8	7	5
				8

Because the upper digit (6) in the tens column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (16).

Place value	thousands	hundreds	tens	ones
		3	16
			6	13
	7	4	7	3
-	2	8	7	5
				8

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

Place value	thousands	hundreds	tens	ones
		3	16
			6	13
	7	4	7	3
-	2	8	7	5
			9	8

Because the upper digit (3) in the hundreds 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 (13).

Place value	thousands	hundreds	tens	ones
	6	13
		3	16
			6	13
	7	4	7	3
-	2	8	7	5
			9	8

Subtract the numbers in the hundreds column from the top number:
13-8=5

Place value	thousands	hundreds	tens	ones
	6	13
		3	16
			6	13
	7	4	7	3
-	2	8	7	5
		5	9	8

Subtract the numbers in the thousands column from the top number:
6-2=4

Place value	thousands	hundreds	tens	ones
	6	13
		3	16
			6	13
	7	4	7	3
-	2	8	7	5
	4	5	9	8

The solution is: 4,598
