title: Sign magnitude, One's complement, Two's Complement
body: <p>So my professor has a question to make a list of all positive and negative numbers that can be represented in One's, two's complements, and sign magnitude: </p>
  
  <p><strong>Using 4 bit numbers, for example (5)10 = ( 0101)2
  Write all positive numbers and all negative numbers that can be represented with four bits in sign-magnitude, one’s complement, and two’s complement.</strong> </p>
  
  <p>Now, I am not looking for the answer just clarification. </p>
  
  <ul>
  <li>for sign magnitude, the first bit represents the sign of the number.
  so in the example provided, negative five is -5= (1101), The ones
  complement = (0101) the twos complement (1010)</li>
  <li>Sign magnitude only allows for three bits to show number and one for
  the sign (the leading bit from right to left.) This would mean that
  we only have 8 combinations.  so that is numbers from 0-7 and -0-
  (-6) Ones and twos we have 16?  so 0-15 and -0-(-15)</li>
  </ul>
  
  <p>can someone explain this question better?</p>
