Hello all, this will be one of my first posts on this site so tell me if I'm doing anything wrong. On to the topic, when I enter the equation: 6/2(1+2)    It will then make it into: 6/(2(1+2))    I looked this up and it appears to be using an old rule (so I am told). Is there any way to change this? Thanks for your reply!

Nope, no way to change it. But I also don't see why you'd need it, you can usually adjust everything by just using "(" and ")"

The omitted multiplication sign has higher priority than multiplication, division and other 2 operations.

You need to type the expression exactly (with multiplication sign or parenthesis - the calc doesn't know your thoughts), because 6/2(1+2) is undefined (this expression has 2 different meanings). Fortunately, Casio add the parenthessis automatically so the expression is exactly defined for calculation.
