Common Mistakes

⚠️

Mistake: Using regular numbers instead of superscript for ordinals and exponents

Fix: Use ² (²) and ³ (³) for powers in formulas, and ª/º for ordinals (1ʳ, 2˚). Regular numbers are baseline-aligned and change the meaning.

⚠️

Mistake: Using superscript letters instead of the ordinal indicator

Fix: The feminine ordinal indicator ª (ª) is not the same as superscript 'a'. Use ª for Spanish ordinals like 1ª (primera) and º for 1º (primero).
