![-7 + (12 - 3[50 - 4(2+3)])](/tpl/images/0074/2932/f46ea.png)
this expression step by step:
![3\cdot [50-4(2+3)]=3\cdot 30=90;](/tpl/images/0074/2932/68eac.png)
![12-3\cdot[50-4(2+3)]=12-90=-78;](/tpl/images/0074/2932/67505.png)
![-7 + (12 - 3[50 - 4(2+3)])=-7+(-78)=-7-78=-85.](/tpl/images/0074/2932/bbfa8.png)
