A full adder can also be constructed from two half adders by connecting and to the input of one half adder, then taking its sum-output as one of the inputs to the second half adder and as its other input, and finally the carry outputs from the two half-adders are connected to an OR gate.

Vipera berus, also known as the common European adder [3] and the common European viper, [4] is a species of venomous snake in the family Viperidae. The species is extremely widespread and can be found throughout much of Europe , and as far as East Asia . [ 2 ]
A conditional sum adder [3] is a recursive structure based on the carry-select adder. In the conditional sum adder, the MUX level chooses between two n/2-bit inputs that are themselves built as conditional-sum adder. The bottom level of the tree consists of pairs of 2-bit adders (1 half adder and 3 full adders) plus 2 single-bit multiplexers.
A full adder can be constructed from two half adders by connecting A and B (i.e. the inputs of the full adder) to the input of one half adder, connecting the sum from that to an input of the second adder, connecting C i to the other input and taking the carry output of the full adder to be the or of the carry
