@libbyanne40 "the difference is negative eighteen"  can you clarify what difference 
@shahd-owies you assume the result is 18
and then made an error the original has negative 18

triciaal · Answer

@shahd-owies sorry that is not an assumption. By definition the difference is the result from subtraction.   you only have an error
