Step-by-step explanation

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

Place value	thousands	hundreds	tens	ones

	2	4	2	8
-			3	6

2. Subtract the numbers using long subtraction method

Subtract the numbers in the ones column from the top number:
8-6=2

Place value	thousands	hundreds	tens	ones

	2	4	2	8
-			3	6
				2

Because the upper digit (2) 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 (12).

Place value	thousands	hundreds	tens	ones
		3	12
	2	4	2	8
-			3	6
				2

Subtract the numbers in the tens column from the top number:
12-3=9

Place value	thousands	hundreds	tens	ones
		3	12
	2	4	2	8
-			3	6
			9	2

Write 3 in the hundreds place.

Place value	thousands	hundreds	tens	ones
		3	12
	2	4	2	8
-			3	6
		3	9	2

Write 2 in the thousands place.

Place value	thousands	hundreds	tens	ones
		3	12
	2	4	2	8
-			3	6
	2	3	9	2

The solution is: 2,392
