Step-by-step explanation

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

Place value	hundreds	tens	ones

	1	6	7
-		9	2

2. Subtract the numbers using long subtraction method

Subtract the numbers in the ones column from the top number:
7-2=5

Place value	hundreds	tens	ones

	1	6	7
-		9	2
			5

Because the upper digit (6) in the tens 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 (16).

Place value	hundreds	tens	ones
	0	16
	1	6	7
-		9	2
			5

Subtract the numbers in the tens column from the top number:
16-9=7

Place value	hundreds	tens	ones
	0	16
	1	6	7
-		9	2
		7	5

Write 0 in the hundreds place.

Place value	hundreds	tens	ones
	0	16
	1	6	7
-		9	2
	0	7	5

The solution is: 75
