When might you want to add things? Those are all applications suitable for an adder.

ALUs, CRC calculations, and numerical offsets are all things that come to mind in a few seconds, but there are many, many more reasons for adders (not the snakes.... Though, I guess a half adder is good for half a belt, and a full adder is good for exercise ;)).

A half adder is used for the first stage where there is no carry in. The full adder is used for all of the remaining stages, because they require a carry in.
