Lab 6.1
3 a) MUL X is stored at 4 or in binary 00000010
  b) LDI is an unknown instuction
  c) 10
  d) Variable Y is stored at address 2 and is represented
     in binary by 10000010
  e) Variable X is stored at address 4 and is represented	
     in binary by 10000001
  f) Variable W is stored at address 6 and is represented
     in binary by 10000000
  g) LOD 5
     ADD W
     SUB Z
     DIV X
     STO Y

Lab 6.2
9 a) Y = Z * 3 - X
  b) Y = Z + (X-3)
  c) Y = 3(Z/2) - X

Lab 6.3
6. a) LOD Z
      MUL #3
      SUB X
      STO Y

   b) LOD Y
      ADD #5
      DIV #2
      STO X

   c) LOD W
      MUL X
      STO T1
      LOD X
      MUL X
      ADD T1
      STO Z

7. a) Z/2=X
   b) z/2*Y=X
   c) X=Z/2Y

Lab 6.4
7. X = (3*14) + (2/1)
   X = 42 + 2
   X = 44
The book states that this should produce a value of 
43 when the code is played by the simulator.

8. LOD X
   ADD Y
   ADD Z
   DIV #3
   STO W
