do this using the appropriate number of sig figs
320.44 − (3104.1/2.6)
i got -880 as my answer and it said to check my sig figs. I thought it was all the numbers up to the ones place

3104.1/2.6 gives 1193.88 but that answer may have only two sig figs (because of the 2.6) so that rounds to -1.2E3.
-879.6?
I would do it this way.
3104.1/2.6 = -1193.88
-1193.88 = -1.19388E3 (2 s.f.)
+ 320.44 = 0.32044E3
= 0.87344E3 which rounds to 0.9. You are allowed the tenths in the 1.2E3 answer so you are allowed tenths in the answer.
3104.1/2.6 = -1193.88
-1193.88 = -1.19388E3 (2 s.f.)
+ 320.44 = 0.32044E3
= 0.87344E3 which rounds to 0.9. You are allowed the tenths in the 1.2E3 answer so you are allowed tenths in the answer.
I am confused so the answer would be .87?
oh oops i didn't see the e3
-870
