    It's best to draw/record/write down everything you see in a word problem that may come into use. That's what I did to demonstrate this problem. What do you think it is again?

    Incorrect. What Vocaloid meant was to check your signs in the initial application of this problem.

    Start off with -1200 + 900 = ?

    You can even apply it into a calculator w/o the signs… just make sure to keep the negative sign if the greater number is a negative

    Good job! To make it easier-looking with less complex numbers, what's -5 + 3?

    Awesome! So -300 - 350 = ? I think you may have mixed up the numbers with multiplication because a negative times a negative = positive. So it equals to -650, which is A. I apologize for saying it was wrong.. that was my error.
