Answer

170 − 65 =

105

With regrouping: 1 borrow — from the tens

170 − 65 in a column. Above the columns: the values after borrowing — a crossed-out digit is replaced by the number above it; +10 marks a column that received a borrowed ten.
			6	+10
		1	7(was 7, now 6)	0 (was 0, now 10)
	−		6	5
		1	0	5

Column by column: 170 − 65

Ones: 0 is less than 5 — borrow 1 ten: tens 7 → 6; 10 − 5 = 5 — write 5.
Tens: after borrowing, 6; 6 − 6 = 0 — write 0.
Hundreds: nothing to subtract — write 1.

170 − 65 = 105

Second check: 170 − 105 = 65
