  (2-((-5×7)--13))
  ((2-(-5×7))+-13)
  (2-((7×-5)--13))
  ((2-(7×-5))+-13)
  (2+(-13-(-5×7)))
  ((2+-13)-(-5×7))
  (2+(-13-(7×-5)))
  ((2+-13)-(7×-5))
  (-13+(2-(-5×7)))
  ((-13+2)-(-5×7))
  (-13+(2-(7×-5)))
  ((-13+2)-(7×-5))
  (-13-((-5×7)-2))
  ((-13-(-5×7))+2)
  (-13-((7×-5)-2))
  ((-13-(7×-5))+2)
