Using significant figure rules and order of operations: Step 1: $(0.0045 × 20000.0) + (2813 × 12)$ Simplify what is in the parentheses to the proper significant values using multiplication/division significant figure rules. $(90.) + (3.4 × 10^{4})$ Step 2: Add them together using addition/subtraction significant figure rules. The lowest decimal place is no decimal place, and therefore the answer is: 34090
