text: No, wrong... "por" means times, as in 2x4=8 (Dos POR cuatro IGUAL ocho)\n\nson/as I dont understand, the basic math funcions are:\n- (menos) minus\n+ (mas)   plus\nx (Por)   times \n/ (Dividido) divided by\n\na 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".\n\nand y means either an incognit, such as in 2x+3y=4 or the simple and plain "and" of spanish language
