What is 183 − 78?

Answer

183 − 78 =

105

With regrouping: 1 borrow — from the tens

183 − 78 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.
			7	+10
		1	8(was 8, now 7)	3 (was 3, now 13)
	−		7	8
		1	0	5

Column by column: 183 − 78

Ones: 3 is less than 8 — borrow 1 ten: tens 8 → 7; 13 − 8 = 5 — write 5.
Tens: after borrowing, 7; 7 − 7 = 0 — write 0.
Hundreds: nothing to subtract — write 1.

183 − 78 = 105

Second check: 183 − 105 = 78
