OpenStudy (clongoria2):
which one equals -46?
OpenStudy (minecraft40952):
-22+-26
OpenStudy (clongoria2):
-22 + -26 = -48
When adding TWO negative numbers just ignore the negative sign
After you add them just put the negative sign back
OpenStudy (clongoria2):
So -21 + -25 | 21 + 25 = 46 = -46
OpenStudy (clongoria2):
C is your correct answer
