Well, to me, having 2(9+3), with the 2 right next to the parenthesis, with no space or multiplication symbol, implies that the 2 is multiplied to whatever is in the parenthesis

That would be the case if (a) there were no operations preceding the 2 or (b) there is a preceding addition/subtraction operation. In other words:

2(9+3) = 2 x (9+3) = 2 x 12 = 24

48+2(9+3) = 48 + 2 x (9+3) = 48 + 24 = 72

48/2(9+3) = 48 ÷ 2 x (9+3) = 24 x 12 = 288
