9+8*[7+6*(5+4*3)-2*1]-10*10


Răspuns :

9+8*[7+6*(5+4*3)-2*1]-10*10 = 
Intai rezolvam paranteza rotunda
 (5+4*3) = 5 + 12 = 17
=> 9+8*(7+6*17-2*1)-10*10 =
Aici iar rezolvam paranteza rotunda . 
=> (7+6*17-2*1) =
7+102-2 = 109 - 2 = 107
=> 9+8*107-10*10 =
9+856-100 = 865 - 100 = 765
9+8*[7+6*(5+4*3)-2*1]-10*10=> rezolvi intai din paranteza rotunda, / sau * apoi - sau +
9+8*(7+6*17-2*1)-10*10=>
9+8* (7+102-2)-10*10=>
9+8* (109-2)-10*10=>
9+8*107-100=>
9+856-100=> 865-100= 765
