See steps

Step-by-step explanation

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

Place value	tens	ones

	3	6
-		9

2. Subtract the numbers using long subtraction method

Because the upper digit (6) in the ones column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (16).

Place value	tens	ones
	2	16
	3	6
-		9

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

Place value	tens	ones
	2	16
	3	6
-		9
		7

Write 2 in the tens place.

Place value	tens	ones
	2	16
	3	6
-		9
	2	7

The solution is: 27
