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.
i have no clue
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?
The same thing is applied to any number :)
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.
