− 7 − ( 50 − ( 24 − ( − 15 ) × 2 ) ) = − 7 − ( 50 − ( 24 − ( − 30 ) ) ) = − 7 − ( 50 − ( 24 + 30 ) ) = − 7 − ( 50 − 54 ) = − 7 − ( − 4 ) = − 7 + 4 = − 3 \begin{aligned} -7-(50-(24-(-15)\times 2)) & = -7-(50-(24-(-30))) \\ & = -7-(50-(24 + 30)) \\ & = -7-(50-54) \\ & = -7-(-4) \\ & = -7+4 \\ & = \boxed{-3} \end{aligned}
