Your answer doesn't take into account the SF I believe. SF are confusing though.

Standard practice is not to round until the very end of the calculation.
320.55 - (6104.5/2.3)
Put these numbers into your calculator to get
= -2333.580435
Then note that in your division you used a number with only 2 SF. So you round your answer to 2 SF.
= -2300
