Contribuido por: Knapke
  • 1. Evaluate 5x -y: use x=2 and y = 1
  • 2. Evaluate 6y + x; use x=1 and y=5
  • 3. z(-6 + y); use y = -4 and z = 2
  • 4. m - 3p; use m=-4 and p=-6
  • 5. y + z2-y; use y=-6 and z = 5
  • 6. y-3-yz; use y=5 and z=6
  • 7. p-n*(n/5); use n=-5 and p=1
  • 8. z-1- (x + y); use x=6, y=1 and z=-5
  • 9. np + n + (m/6) - n; use m=6, n=-6, and p=-1
  • 10. y + z + 2 - z + 5 - x; use x=3, y=1, and z=4
