Is 25+45-(250+365-2) is expression

Dear Student,
As per i can understand your question is unclear or incomplete have some missing information.
But let me explain you as much as i understand it.
$$\begin{gathered} 25+45-(250+365-2) \\ Let us first solve inside the bracket \\ (250+365-2) = 615-2 =613 \\ Then put it in bracket and lets solve it again \\ 25+45-\left(613\right) \\ =70-(6130 \\ =70-613 \\ =-543 \end{gathered}$$
Regards.
