title: nand bitwise operation in MIPS Assembly
body: <p>I've been trying to figure out how to do a nand bitwise operation in assembly but have been unsuccessful.  I'm tried to write a logic gate simulator that will essentially produce this truth table for inputs A and B</p>
  
  <pre>
  
     A  |   B  ||  F
    -----------------
     lo |  lo  ||  hi
     lo |  hi  ||  hi
     hi |  lo  ||  hi
     hi |  hi  ||  lo
  </pre>
  
  <p>I've tried everything.</p>
  
  <pre>
    and  $t3,$t1,$t  
    not  $t4,$t3
  </pre>
  
  <p>Does not produce the correct output</p>
