Hello. I am studying turing machines. I know that a turing machine can read/write a symbol, move to left to right, and enter into a serie of states. But i don't know how the transition function works. I don't know how the turing machine can reference values when it only performs sequentialy operations. Please, give me an example explaining the addition of two binary numbers using it. Explain me also more about states. Thanks.
