    I am trying to figure out the proper answer in significant figures for this, I'm not sure which rule I follow, the addition/subtraction rule or the multiplication/division rule?

    320.5 - (6104.5 / 2.3)

    I'm wondering if the answer should be -2333.6 or -2379.5?

    Could you please show work?

    Thank you!
