85 + 36 in a column. Carries are the small circled digits above the columns.
		1carry	1carry
			8	5
	+		3	6
		1	2	1

Column by column: 85 + 36

Ones: 5 + 6 = 11 — write 1, carry 1.
Tens: 8 + 3 + 1 = 12 — write 2, carry 1.
Hundreds: the carried 1 — write 1.

85 + 36 = 121

Second check: 121 − 85 = 36
