title: Two's Complement Binary Range for 8-Bit
body: <p>For an 8-bit cell that uses two's complement binary representation for storing SIGNED integers, what is the range of integers for this cell as written in binary?</p>
  <p>I had 00000000 to 11111111 because I thought the decimal range was 0 to -1, but I don't think I'm approaching the problem the right way.</p>
