(48÷2)(9+3) is not valid syntax for arithmetic!
- at least it wasn't when they were trying to educate me.
in algebra, with the numbers replaced by letters, it may work..but not in arithmetic...that's why we have the multiplication sign.
sorry to spoil your fun, but there it is.
parenthesis is also a sign of multiplication so does an asterisk, but mostly in algebra parenthesis is used to replace the multiplication sign x so not to misunderstood x which is the unknown, 2x + 2x(x+1) find x, as for 2x1=2
in this case (48÷2)(9+3) involving more than one operation, a parenthesis is used which means 48÷2=24 and then 9+3=12...final operation is to multiply 24 and 12 which is 288
