That was just a question--not necessarily the answer. I really need to see the print page. I'm pretty sure this is not a math issue but I still need to see the print. I asked that question because I thought there was English in this, but apparently there is not. And if it's all Spanish there will be no and, for, the, with because those are English words. The reader will use context and know that an accented foreign letter is not going to turn up in the middle of math text. I still need to see the print in order to provide a complete answer.
