2 x{100+7+[300-5 x (2730-25-108)]}

Ajutati-ma si cu:
a.64+{3+5 x [29+2 x(4831-30 x 166)]}
b.6225-2 x{ 5 x [2 x(107 + 13)+3 x (104+8)]}

2(100+7+(300-5(2730-25-108)))=2(107+(300-5×2597))=2(107+(300-12985)))=2(107-12685)=-25156
 
a)64+(3+5(29+2(-4980+4831)))=64+(3+5(29+2×(-149))=64+(3+5(29-298)=64+(3+(-269×5))=64+(3-1345)=64-1342=-1278
 
b)6225-2(5(2×120+3×112))=6225-2(5(240+336))=6225-2(576×5)=6225-2880=3345
