Arithmetic Operation in Single Membrane

Membrane system is a computing model which imitates natural process at cellular level. In this system all objects can evolve in a maximal parallelism and distributed manner. It is an unconventional computing model, many hard computational problems have been investigated recently. However, simple computer operations, such as basic arithmetic operations, have not been addressed much. This paper gives a more effective method to implement arithmetic operations. It uses only one membrane and easy rules, and the output result can be easily used as the input for further operations.
