What is 70 − 12?

Answer

70 − 12 =

58

With regrouping: 1 borrow — from the tens

70 − 12 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
		7(was 7, now 6)	0 (was 0, now 10)
	−	1	2
		5	8

Column by column: 70 − 12

Ones: 0 is less than 2 — borrow 1 ten: tens 7 → 6; 10 − 2 = 8 — write 8.
Tens: after borrowing, 6; 6 − 1 = 5 — write 5.

70 − 12 = 58

Second check: 70 − 58 = 12
