    From my understanding braces and brackets just more ordering to the expression. Do you have an example of an expression that can't be done with just parenthesis? – tinstaafl Nov 02 '16 at 04:48
  • Mmm... you are right! Will change the {} [] with () thanks! :D – albita Nov 02 '16 at 05:02

When evaluating simple arithmetic expressions, [] or {} are just a notational variant of () to make matching parentheses easier. So you could simply replace them by () and then proceed with that.

There are many corners in Mathematics where these symbols would mean completely different things, e.g. [] for floor, equivalence class, vector, … or {} for fractional part, set, … So it would be wrong to say that any mathematical expression retains its semantics by the above replacement. Be sure you know what kinds of expressions you're dealing with.
