Question

The high temperature one day was -3 °F.The low temperature was -7 °F. What wasthe difference between the high and lowtemperature for the day?

The question asks about the difference between the high (Th) and the low temperature (Tl) for the day, i.e. we must compute the difference:

$T_h-T_l\text{.}$

Replacing the values of the statement, and computing we find that the difference is:
