OpenStudy (anonymous):

Is 2 an option?

OpenStudy (gabylovesyou):

yes @AmauryP and @lgbasallote 4 * -1 is -4

OpenStudy (lgbasallote):

and what's 2 * -3?

OpenStudy (gabylovesyou):

-6

OpenStudy (lgbasallote):

so what's - 4 - (-6)?

OpenStudy (gabylovesyou):

2 ;lol

Yep it's 2. Because if you plug the X and Y in it'll end up being 4(-1)-2(-3) 4 and -1 is -4. 2 and -3 is -6 so -4 - -6 is -4 + 6 which ends up to 2.

OpenStudy (lgbasallote):
