5.2 Rules



We need to keep four rules in mind when working with numbers.

Select each tab to see the four general rules about numbers. 
You learned that cien = 100.
For numbers 101 and beyond, use ciento followed by the number in question.
For example: 101 = ciento uno, 102 = ciento dos.
Cien and ciento are used with masculine and feminine nouns. For example: Tengo cien (100) libros. Tengo ciento dos (102) camisetas.

However, the numbers 200-900 need to agree with the noun they modify: For example: Tengo doscientos libros. Tengo doscientas camisetas.
Just like English, we say large numbers by combinations. For example, in English we would say one hundred forty-five for the number 145. In Spanish, we do the same. For example:

145 = ciento cuarenta y cinco 1020 = mil veinte (1000 + 20)
120 = ciento veinte 1460 = mil cuatrocientos sesenta (1000 + 400 + 60)
267 = doscientos sesenta y siete 2009 = dos mil nueve (2000 + 9)
350 = trescientos cincuenta 3500 = tres mil quinientos (3000 + 500)

Try to say the year you were born.
For example, if you were born in 2003 you would say dos mil tres!
Numbers can be difficult to remember, so look for word connections to help you remember: For example, seis = 6, sesenta = 60, seiscientos = 600.
All of these words have similar beginning sounds and the actual word seis appears in seiscientos.
In fact, if you break up the word seiscientos you will see it is two words in one: seis + cientos = seiscientos = 600

Examples


noventa = 90 novecientos = 900
ocho = 8 ochenta = 80 ochocientos = 800
siete = 7 setenta = 70 setecientos = 700
tres = 3 trece = 13 trescientos = 300
cinco = 5 cincuenta = 50
