Best ResponseYou've already chosen the best response.0So, if you were trying to do this problem in your head, not using pen/paper/calculator, it isn't supereasy to add 2.5 and 4.9 inside the parenthesis. But it would be easier if the parenthesis was around two different numbers... two that are easier to add in your head.
