Step-by-step explanation

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

Place value	thousands	hundreds	tens	ones

	2	7	2	2
-			2	8

2. Subtract the numbers using long subtraction method

Because the upper digit (2) in the ones 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 (12).

Place value	thousands	hundreds	tens	ones
			1	12
	2	7	2	2
-			2	8

Subtract the numbers in the ones column from the top number:
12-8=4

Place value	thousands	hundreds	tens	ones
			1	12
	2	7	2	2
-			2	8
				4

Because the upper digit (1) 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 (11).

Place value	thousands	hundreds	tens	ones
		6	11
			1	12
	2	7	2	2
-			2	8
				4

Subtract the numbers in the tens column from the top number:
11-2=9

Place value	thousands	hundreds	tens	ones
		6	11
			1	12
	2	7	2	2
-			2	8
			9	4

Write 6 in the hundreds place.

Place value	thousands	hundreds	tens	ones
		6	11
			1	12
	2	7	2	2
-			2	8
		6	9	4

Write 2 in the thousands place.

Place value	thousands	hundreds	tens	ones
		6	11
			1	12
	2	7	2	2
-			2	8
	2	6	9	4

The solution is: 2,694
