Hi guys, I have a simple question but it doesn’t seem that simple. I understand that and why 3(x+4) times 2(x+3) gives me (3x+12) times (2x+6) with the brackets written. Indeed, brackets are important here. However, what I don’t understand is why 3(x+4)+2(x+3) (note that only the multiplication sign is replaced by the addition sign) gives 3x+12+2x+6 straight without the brackets ( I know that we do 3(x+4) first then 2(x+3) ). Isn’t it supposed to be expanded to (3x+12) + (2x+6) with the brackets just like in the case of multiplication above? I thought since 3(x+4) and 2(x+3) are together in one expression and they do not stand alone, the brackets therefore are mandatory in the expanded form since 3(x+4) is viewed as a set and 2(x+3) another set?
