Step-by-step explanation

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

Place value	tens	ones

	3	5
-	2	7

2. Subtract the numbers using long subtraction method

Because the upper digit (5) 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 (15).

Place value	tens	ones
	2	15
	3	5
-	2	7

Subtract the numbers in the ones column from the top number:
15-7=8

Place value	tens	ones
	2	15
	3	5
-	2	7
		8

Subtract the numbers in the tens column from the top number:
2-2=0

Place value	tens	ones
	2	15
	3	5
-	2	7
	0	8

The solution is: 8
