Wow! That’s interesting. One does the division first, and the other does the multiplication first.
Which is more standard? I think because there’s no * between the 2 and the parenthesis, you do the multiplication first.
I don’t know what is correct by the rules but in computer science it is parenthesis first followed by multiply or divide followed by add or subtract with whichever has precedence calculating left to right. In other words.
(48/2) * (9+3) = 288
