Question 1128498

In a chemistry class, students were learning about boiling point of various elements.Reuben has compiled a table that gives boiling points of each of various elements.

The lowest boiling point is of Element X:  – 200 degrees Fahrenheit. 
The highest boiling point is of Element Y: 550 degrees Fahrenheit

Find the difference between the lowest and highest boiling point.
I know how to calculate the difference.
-200 – 550 = -750.
 I am not sure if the answer is written as a negative or positive. Isn’t difference in temperature always written as its absolute value? 
Will the answer be – 750 F  or 750 F ? 

Would greatly appreciate if you could explain what the correct answer is
<pre>To find the difference between the HIGHEST and the LOWEST boiling points, you just SIMPLY SUBTRACT the LOWER of the 2 temperatures from the HIGHER of the 2 temperatures. 
This gives us: {{{highlight_green(matrix(1,6, 550 - - 200, "=", 550 + 200, "=", 750^o, F))}}}
