title: decimal conversion using 5 bit two's complement
body: <p>i am asked to show the calculation of 11+6 using 5 bit two's complement. i find some rules confusing but have come up with the answer as shown below. please let me know if it is correct or what needs to be done if it is wrong.</p>
  
  <p>two's complement of 11 is<br>
  01011<br>
  two's complement of 6 is<br>
  00110<br>
  now adding them using carriers if required:</p>
  
  <p>01011 -----11 in binary<br>
  00110  -----6 in binary<br>
  10001  ---total<br>
  which in decimal is 17. is this the correct method of working out??? because my result in binary shows 10001. isn't 10001 supposed to mean -1 because the first bit in two's complement is a sign bit. please help me solve this if it is wrong. thanks for your help.</p>
