But I can't think of an adder (mechanical or electronic) or indeed a way of adding by hand which is not symmetical on the 2 inputs.

Was this not because subtraction and division done electronically in binary at the simplest level still used an adder albeit with say the "two's compliment" so you would still need to define which input was which ?
