The usual rule of thumb only says that you get one significant figure, not two, because both 9 and 2 only have one significant figure.

Doing addition for both sets would give you 10.02 and 11.98, which still presents similar problem as that in my original post. Perhaps I am confused because I do not understand the rules for rounding and the greater context surrounding it. Can you comment on that?
