  • Do not assume all numbers are positive integers or integers at all unless explicitly stated.
  • Be aware of mathematical exceptions and how they can impact the sufficiency of data provided.
  • Analyze each statement independently without carrying information over from one to the other.
  • Learning from mistakes is essential for improvement; always seek to understand and correct errors rather than dismissing them.
