Ok, so all we have to do is find the two to add, right?

So because this is OpenStudy and I can get in trouble for a direct answer.  we both will have to get a calculator find different number to calculate.

But don't worry I have been looking and I found it, but I really need you to find it, so i'm not giving direct answer.
