i dont get this math problem (equation)??

OpenStudy (anonymous):

\[23-d=11\]

OpenStudy (anonymous):

i did 23+11 and got 34 then the answer should be -11 right???

OpenStudy (anonymous):

and this person did 23-11 why?? i thought u had to do the opposite

OpenStudy (anonymous):

-d = 11-23 d = (11-23)(-1) d = 23-11 d = 12
