Answer

130 − 52 =

78

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

130 − 52 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)	0 (was 0, now 10)
	−		5	2
			7	8

Column by column: 130 − 52

Ones: 0 is less than 2 — borrow 1 ten: tens 3 → 2; 10 − 2 = 8 — write 8.
Tens: after borrowing, 2; 2 is less than 5 — borrow 1 hundred: hundreds 1 → 0; 12 − 5 = 7 — write 7.
Hundreds: after borrowing, 0 — a leading zero is not written.

130 − 52 = 78
