Using 'de' with large numbers
When you follow 'billones' with a specific thing (like people or dollars), you must put the word 'de' in between. For example: 'tres billones de dólares'.
The 'Billion' Trap
Mistake: “Using 'billones' to mean the English 'billions' (1,000,000,000).”
Correction: In Spanish, a 'billón' is a million millions (1 followed by 12 zeros). If you want to say the English 'billion' (9 zeros), say 'mil millones' (a thousand millions).
