[!TLDR]

Full adder: $Sum=A\oplus B\oplus C_{in}$ , $C_{out}=AB+BC_{in}+AC_{in}$ .

A full adder adds three input bits: the two operand bits $A$ and $B$ and a carry-in $C_{in}$ from the previous stage. It produces a Sum and a carry-out $C_{out}$ .

Truth table:

A	B	Cᵢₙ	Sum	C_out
0	0	0	0	0
0	0	1	1	0
0	1	0	1	0
0	1	1	0	1
1	0	0	1	0
1	0	1	0	1
1	1	0	0	1
1	1	1	1	1

Boolean expressions: $Sum = A\oplus B\oplus C_{in}$ ; $C_{out} = AB + BC_{in} + AC_{in}$ . …
