Common Mistakes

⚠️

Mistake: Using hyphens and greater-than signs (->) instead of proper arrow symbols

Fix: Use → (→) for right arrow in mathematical mappings. The ASCII -> looks unprofessional and does not render consistently for mathematical notation.

⚠️

Mistake: Confusing single arrows with double arrows in logic notation

Fix: Use → (→) for function mappings and chemical reactions. Use ⇒ (⇒) for logical implication (P ⇒ Q). They have distinctly different meanings in mathematics.
