Common Mistakes
⚠️
Mistake: Using programming operators instead of proper math symbols
Fix: In mathematical content, use ≠ (≠) not !=, ≤ (≤) not <=, × (×) not x or *. Programming operators are meant for code, not mathematical notation.
⚠️
Mistake: Confusing similar math symbols with different meanings
Fix: Use ≅ (≅) for congruence, ≈ (≈) for approximate equality, ∼ (∼) for similarity. Each symbol has a distinct mathematical meaning.
