 --- Cheyenne, Wyoming
Solving (a): Inequality to compare both temperatures
From the given temperatures, we can conclude that:
 or
 or 
Because
 i.e. 1 is greater than -2
 i.e. 1 is greater than -2
or
 i.e. -2 is less than 1
 i.e. -2 is less than 1
Solving (b): Inequality to compare the absolute values of the temperatures
We have:


The absolute values are:




By comparison:
 or
 or 
Because
 i.e. 2 is greater than 1
 i.e. 2 is greater than 1 
or
 i.e. 1 is less than 2
 i.e. 1 is less than 2
