Step-by-step explanation

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

Place value	hundreds	tens	ones

	2	9	2
-		3	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 (9) in the next number place which becomes (8) and get (12).

Place value	hundreds	tens	ones
		8	12
	2	9	2
-		3	8

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

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

Subtract the numbers in the tens column from the top number:
8-3=5

Place value	hundreds	tens	ones
		8	12
	2	9	2
-		3	8
		5	4

Write 2 in the hundreds place.

Place value	hundreds	tens	ones
		8	12
	2	9	2
-		3	8
	2	5	4

The solution is: 254
