Step-by-step explanation

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

Place value	hundreds	tens	ones

	1	0	4
			2
-			8

2. Subtract the numbers using long subtraction method

Because the upper digit (4) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (10) which becomes (09) and get (14).

Place value	hundreds	tens	ones
	0	9	14
	1	0	4
			2
-			8

Subtract the numbers in the ones column from the top number:
14-2-8=4

Place value	hundreds	tens	ones
	0	9	14
	1	0	4
			2
-			8
			4

Write 9 in the tens place.

Place value	hundreds	tens	ones
	0	9	14
	1	0	4
			2
-			8
		9	4

Write 0 in the hundreds place.

Place value	hundreds	tens	ones
	0	9	14
	1	0	4
			2
-			8
	0	9	4

The solution is: 94
