How many exercises do I have to complete ?

I'm taking PoMA-Rudin, do I have to complete all the exercises after every chapter to be regarded as understanding the material ?
Does all the tools for solving the exercises lie in the material? Because I feel many problems require more than the textbook. Thanks.

rudin's exercises are known to be pretty difficult and may require more ingenuity than just simply applying the theorems and propositions in the text. you shouldn't have to do all of the exercises either. i would say scan through the exercises and find ones that you don't know how to do right away and those that seem particularly interesting and work on those.
