Step-by-step explanation

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

Place value	thousands	hundreds	tens	ones

	3	0	1	8
				6
-			1	8

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	0	1	8
				6
-			1	8

Subtract the numbers in the ones column from the top number:
18-6-8=4

Place value	thousands	hundreds	tens	ones
			0	18
	3	0	1	8
				6
-			1	8
				4

Because the upper digit (0) in the tens column is too small to get a positive difference, borrow 1 from the number to the left (30) which becomes (29) and get (10).

Place value	thousands	hundreds	tens	ones
	2	9	10
			0	18
	3	0	1	8
				6
-			1	8
				4

Subtract the numbers in the tens column from the top number:
10-1=9

Place value	thousands	hundreds	tens	ones
	2	9	10
			0	18
	3	0	1	8
				6
-			1	8
			9	4

Write 9 in the hundreds place.

Place value	thousands	hundreds	tens	ones
	2	9	10
			0	18
	3	0	1	8
				6
-			1	8
		9	9	4

Write 2 in the thousands place.

Place value	thousands	hundreds	tens	ones
	2	9	10
			0	18
	3	0	1	8
				6
-			1	8
	2	9	9	4

The solution is: 2,994
