Question

2×{100+7×[300-5(2730-25×108]}-37×2×5

Answer 1

2*{100+7*[300-5*(2730-2700)]}-370=

=2*{100+7*[300-5*30)]}-370=

=2*(100+7*150)-370=

-2*(100+1050)-370=

=2*1150-370=

=2300-370=

=1930

Answer 2

2 x {100+7 x[300-5(2730-2700)]}-37 x 2 x 5
2 x[100+7 x(300-5 x 30)]-37 x 2 x 5
2 x[100+7 x(300-150)]-37 x 2 x 5
2 x (100+7 x 150)-37 x 2 x 5
2 x (100 + 1050)-37 x 2 x 5
2 x 1150 - 37 x 2 x 5
2300 - 370
1930
