1. One is un before a masculine noun, una before a feminine noun: un libro, una casa. The Spanish words for 21, 31, 41, etc., also obey this rule:
| veinte y un(veintiún) cuadernos | cuarenta yun hombres |
| veinte y una(veintiuna) plumas | sesenta yuna mujeres |
2. The numbers 16 to 19 and 21 to 29 may be written as three words or as one word:
| diez y siete | veinte y nueve |
| or páginas | or chicos |
| diecisiete | veintinueve |
Remember that the following words take accent marks: dieciséis, veintiún, veintidós, veintitrés, veintiséis.
3. Except for 1, 21, 31, etc., Spanish number-words do not change in gender: cuatro casas, cincuenta hombres, etc.
Exercise: Write the Spanish words for the numbers in parentheses. Where two blanks are given, write the number in two ways. (Be careful to notice the gender of nouns preceded by 1, 21, 31, etc.)

5. In numbers 101 to 199, cientois used.
6. 101 followed by a masculine noun is ciento un; 101 followed by a feminine noun is ciento una. The form ciento uno is used only in counting or when referring to a masculine noun that is understood but not expressed:

trescientas cuarenta y cinco casas
8. The conjunction y (and) occurs only between the tens and units digits:
| cuarenta y cinco | 45 |
| but: | |
| tres mil siete | 3007 |
