Why do we need to have 'que'?
Tener means to have, but tener que + infinitive means have to + infinitive. :)
Tengo trece gatos. - I have three cats.
Tengo que leer el libro. - I have to read the book.
Hope this helps.
Muy bueno, gracios!!!
De nada. ^_^
Just learn the formula: tener que + infinitive.
Again, I get dinged for using the formal you. Is there some clue here that this a friend, family or a child I'm talking to?
I think it's the absence of clues that is the clue. I get dinged when the sentence says "sir" and i use the informal. So if it's not "sir" or "ma'am" it's probably safe to assume it's not formal.
I think that you should be able to use the formal.
sometimes, it's possible to reverse parts of the sentence. why, in this case, is this incorrect? "Tienes que pagar cuántos pesos?"
