What answer should be reported, with the correct number of significant figures, for the following calculation:
(965.43 x 3.91) + 9413.4136
I got 13189 as an answer. Can someone let me know if this is right?

For the (), you multiply and then to 3 sig figs for that part=3770. For the addition (3770+9413.4136), your sig figs are to the place of the decimal b/c the first answer only goes to the decimal place so answer is 13183 or 1.3183 x 10^4
