text: what does por,son/as,and y in spanish? that has to do with math no, wrong... "por" means times, as in 2x4=8 (dos por cuatro igual ocho)  son/as i dont understand, the basic math funcions are: - (menos) minus + (mas)   plus x (por)   times  / (dividido) divided by  a thing that can be is "sen" (seno) instead of "son" and means sinus. if i am in the correct line "as" then is arcoseno and means "arcsin".  and y means either an incognit, such as in 2x+3y=4 or the simple and plain "and" of spanish language
