Con seis seises y los signos de las cuatro reglas

Hasta el 20 me falta el 16. A ver si a alguien lo encuentra...

  1. 1 = 666/666
  2. 2 = 66/66 + 6/6
  3. 3 = 6/6 + 6/6 + 6/6
  4. 4 = 6*6/6 - (6+6)/6
  5. 5 = 66/6 - (6*6)/6
  6. 6 = 66/6 - 6 + 6/6
  7. 7 = (66 + 6 + 6)/6 - 6
  8. 8 = (6*6 + 6)/6 + 6/6 
  9. 9 = 66/6 - (6+6)/6
  10. 10 = (66 - 6)/6 + 6 - 6
  11. 11 = (66 - 6)/6 + 6/6
  12. 12 = 6*6/6 + 6*6/6
  13. 13 = 66/6 + (6+6)/6
  14. 14 = 6 + 6 + 6/6 + 6/6
  15. 15 = (66 - 6 - 6)/6 + 6
  16. 16 = ?
  17. 17 = 66/6 + 6*6/6
  18. 18 = 66/6 + 6 + 6/6
  19. 19 = (66 + 6 + 6)/6 + 6
  20. 20 = 6 + 6 + 6 + (6 + 6)/6

(y que no me haya equivocado)
