The expression can be solved by expanding the bracket and multiplying out the terms


Therefore, the expression can be simplified as;

Alternatively, using the theorem of difference of two squares, which is

Hence,

Answer:

The difference between the 2 different temperatures.
The key word difference refers to subtraction.
So 18 - ( - 13 )
Subtracting a negative is the same as adding the positive.
So 18 + 13
Solve the statement to get:
31
