Answer 5

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?

Answer 6

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

Answer 7

i have no clue

Answer 8

Start off with -1200 + 900 = ?

Answer 9

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

Answer 10

-300

Answer 11

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

Answer 12

The same thing is applied to any number :)

Answer 13

-2

Answer 14

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.

Answer 15

So awesome job! A is the correct answer :)
