With regrouping: 2 borrows — from the tens and the hundreds

138 − 69 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.
		0	12	+10
		1(was 1, now 0)	3(was 3, now 12)	8 (was 8, now 18)
	−		6	9
			6	9

Column by column: 138 − 69

Ones: 8 is less than 9 — borrow 1 ten: tens 3 → 2; 18 − 9 = 9 — write 9.
Tens: after borrowing, 2; 2 is less than 6 — borrow 1 hundred: hundreds 1 → 0; 12 − 6 = 6 — write 6.
Hundreds: after borrowing, 0 — a leading zero is not written.
