what value of D makes -25 - (-16)=D a true sentence?

OpenStudy (anonymous):

-25 + 16 = 9, so 9 if I am reading the question correctly?

OpenStudy (anonymous):

i think the number would be negative since the biggest number is 25 and with a negative integer.

OpenStudy (anonymous):

yeah im sorry it should be -9, basic algebra gets me all the time.

OpenStudy (anonymous):

oh ok. :)
