    1)You must subtract the two numbers.
    -114 – (-42)
    2) when you are subtracting by a negative number, it is just like adding, so you can just change the equation too:
    -114 + 42

    Answer

    -72

    Step-by-step explanation:

    The difference between each can be achieved by subtracting -42 (the freezing point of the acid) to -114 (the freezing point of the alcohol).

    From there, we get the equation -114 – -42, which then leads to equal -72.

    A way I check this is that I go back and add our answer to the lowest term, which becomes -42 + -72, which does, in fact, equal -114.

    So your answer is -72.
