title: Tmax and Tmin of two's complement
body: <p>I understand to get two's complement of an integer, we first flip the bits and add one to it but I'm having hard time figuring out Tmax and Tmin?</p>
  
  <p>In a 8-bit machine using two's compliment for signed integers how would I find the maximum and minimum integer values it can hold?</p>
  
  <p>would tmax be =<code>01111111</code>? and tmin =<code>11111111</code>?</p>
