Always the Same Form
Unlike the numbers 'uno' or 'cien,' the word 'treinta' never changes its form to match the gender (masculine or feminine) of the thing you are counting.
Writing Higher Numbers
Mistake: “Escribir treinta y uno (writing it as one word).”
Correction: Numbers from 31 to 99 are written as three separate words: 'treinta y uno'. Only numbers 16 through 29 are usually one word (e.g., 'dieciséis', 'veinticinco').
