Answer

78 + 74 =

78 + 74 in a column. Carries are the small circled digits above the columns.
		1carry	1carry
			7	8
	+		7	4
		1	5	2

Column by column: 78 + 74

Ones: 8 + 4 = 12 — write 2, carry 1.
Tens: 7 + 7 + 1 = 15 — write 5, carry 1.
Hundreds: the carried 1 — write 1.

78 + 74 = 152

Second check: 152 − 78 = 74
