title: "Calculations" of 6-digit octals in 8's complement, in layman's terms?
body: <p>How does one find the postive/negative range of a 6-digit octal in 8's complement? From what I understand, it's simply half - 1:</p>
  
  <p><code>000001 - 377777 positives, 400000 - 77777 negatives</code></p>
  
  <p>Would 377777 be the highest positive, and 777777 the highest negative number?</p>
  
  <p>If that is correct, it seems to me that 377777 and 777777 are complements of each other. However, from what I've read, to find the complement, subtract the number from the base. Doing that, 377777 would equal:</p>
  
  <p><code>7 - 3 = 4</code></p>
  
  <p><code>7 - 7 = 0</code></p>
  
  <p><code>7 - 7 = 0</code></p>
  
  <p><code>7 - 7 = 0</code></p>
  
  <p><code>7 - 7 = 0</code></p>
  
  <p><code>7 - 7 = 0</code></p>
  
  <p><code>= 400000</code></p>
  
  <p>This shows 400000 is the complement of 37777 (which appears inverse to me).</p>
