In general, you write the numbers 16-19 and 21-29 in one word. The numbers 16, 22, 23 and 26 have accents on the last syllable: in Spanish we have a rule called “chord” that usually consists of words around the name to “match” the name of the sex and number. After experiencing the Spanish numerals, you can sound like a native Spanish speaker by paying attention to the nuances of speech and writing numbers. Here are the rules to remember when using numbers of cardinals in Spanish: you will learn the remaining verbs with your grids stretched by form of tense, and the pronouns begin to become more and more familiar, and that is the correspondence. You only use the conjunction y (and) for numbers between 16 and 99. You do not use it directly by the hundreds: you use numbers of cardinals when you express the first part of an address: Indirect pronouns: me, te, le, nos, os, les. The/them change to “se” when they go in front of “lo/la/los/las”, but this has nothing to do with an agreement. Ciento (100) is cien before the names of both sexes and before the numbers mil and millones. Before all other numbers, use ciento. One (one) that you do not use before cien (to) or mil, arrives before millón.
If a noun follows millón, place the preposition of between millón and the noun. Millón loses its plural accent: now that we have dealt with how the articles correspond to the nouns they return, we can agree on the adjectives. A noun is almost always used with an article before and often with an adjective behind. Remember that the noun is the center of this relationship and that articles and adjectives should match the noun in gender and number. Unlike nouns, articles and adjectives can change — they are like chameleons, as they take the gender and number of the name they are connected to. We say: the rose blanca and el caballo pardo or el hombre alto and the mujer alta. Can you see how spanish articles precede the noun and descriptive adjectives (colored adjectives are perfect examples) follow the noun? Let`s make the previous examples in the plural, that is, if Rosas rosas and Caballo becomes Caballos, we must match the articles and adjectives with the noun. Remember that the name determines the gender of the modifiers; So we read: roses blancas and go caballos pardos. Look at these other examples with larger numbers: if it ends on an -e or an ista, the sex does not change, but add an -s for the plural. Example: verde/s (green), idealista/s (idealistic). Exception: for adjectives that end in z in the singular, change z to c before adding pluralistic rounding. Interpellation – these words express a reaction and are very independent: Bueno, wow..
