This problem is providing a mathematical expression which the result should be expressed with the correct significant figures. At the end, the result is 1209.0 because of the following:
<h3>Significant figures:</h3>
In science, the use of significant figures is crucial as long numbers are not necessarily required when reporting a numerical value, for that reason the importance of reporting measurements with the correct number of significant figures.
In the case of additions, we perform the normal operation as the first step:
1204.2 +4.79613 = 1208.99613
Next, we round the result to the least number of decimal places, in this case one because 1204.2 has just one decimal place, unlike the 4.79613 which has five, so that we round the 8 up to 9 and leave a 0 as the only decimal place:
1209.0
