2. 16  29  numbers 16  29 have two options  17 = diez y siete or diecisiete  (z  c)(y  i)  24 = veinte y cuatro orveinticuatro  (drop the “e”) (y  i)  ISSUE: when the second number is one syllable (dos, tres, seis) you must add an accent mark when it becomes one word)  veintidósveintitrésveintiséis

3. Agreement  With numbers 2  100 you never have to worry about agreement  With number 1 use uno with no noun, un with masculine nouns and una with feminine nouns  For numbers 200  900 you have agreement when referring to a specific item  Tenemos doscientos libros.  Tenemos trescientas computadoras.

4.  “Un” is not used before cien, ciento and mil.  cien libros = one hundred books  mil libros = one thousand books  “mil” never becomes plural  Dos mil libros = two thousand books

5.  You do use “un” with millón  Un millón libros = one million books  “millón” does becomes plural  dos millones libros – two million books  Also notice how the accent is only used over millón

6. “y”  In English we overuse “and” when talking about numbers  Three thousand and forty nine  Two hundred and twenty four  In Spanish DON’T DO THIS!!!  You only use “y” when it’s already part of the number

7. “y”  5,265, 962  Cinco millones doscientos sesenta y cinco mil novecientos sesenta y dos  305  trescientos cinco (no “y”!)

8. cien vs. ciento  Both mean one hundred  Use “cien”  when saying 100 even  Before mil / millón/ millones  Before nouns (cien libros)  Use “ciento”  If there is a number after “100”  101 = ciento uno  170 = ciento setenta
