<gadget id="calculator">50*5</gadget>
<output>250</output>
250   lowest is 42. to find the maximum range we can say the temperature was the lowest for 4 of the 5 days   so   4*42= 
<gadget id="calculator">  4*42</gadget>
<output>168</output>
168.   on the fifth day it is 250-168=281   range is therefore  128-42= 
<gadget id="calculator"> 128-42</gadget>
<output>86</output>
86   answer 86
