Wait!” Juno says. “Can’t subtraction be rewritten using addition? Since order doesn’t matter when we add, can’t we just rewrite the subtraction as addition so we can use any order?” Think about Juno’s idea and then rewrite the following expressions so that it involves only addition. Then use the fact that the numbers are all being added and the order can be changed to find a way to simplify the expression efficiently.
