Answer 1

A){ [ (2³ x 2² + 3 ) ÷ 7 + ( 3 + 15 ÷ 5 ) x 3 ] x 2 ( 19 - 7 ) ÷ 6 }  x 2 + 2² x 3 =
{ [ (8 x 4 + 3 ) ÷ 7 + ( 3 + 3 ) x 3 ] x 2 + 12 ÷ 6 }  x 2 + 4 x 3
{ [ (32 + 3 ) ÷ 7 + 6 x 3 ] x 2 + 2 }  x 2 + 12
{ [ 35÷7+ 18 ] x 2 + 2  }  x 2 + 12
{ [ 5+18 ] x 2 + 2  }  x 2 + 12
{ 23 x 2 + 2 }  x 2 + 12
{ 46 + 2 } x 2 + 12
48 x 2 + 12
96 + 12
108

B) { [ ( 3² x 2² x 7 ) ÷ 3 + 6 ] ÷ 5 } x 3 x 2² =
{ [ ( 9 x 4 x 7 ) ÷ 3 + 6 ] ÷ 5 } x 3 x 4 =
{ [ 252 ÷ 3 + 6 ] ÷ 5 } x 12 =
{ [ 84 + 6 ] ÷ 5 } x 12 =
{ 90 ÷ 5 } x 12 =
18 x 12 = 216

C) { [ ( 2² x 4² x 5 ) ÷ 4 + 10 ] ÷ 3 } x 3 x 2² =
{ [ ( 4 x 16 x 5 ) ÷ 4 + 10 ] ÷ 3 } x 3 x 4 =
{ [ 320 ÷ 4 + 10 ] ÷ 3 } x 12 =
{ [ 80+ 10 ] ÷ 3 } x 12 =
{ 90 ÷ 3 } x 12 =
30 x 12 = 360

D) { [ ( 8 x 4 + 3 ) ÷ 7 + ( 3 + 15 ÷ 5 ) x 3 ] x 2 - ( 19 - 7 ) ÷ 6 } x 2 + 12 =
{ [ ( 32 + 3 ) ÷ 7 + ( 3 + 3 ) x 3 ] x 2 - ( 12 ) ÷ 6 } x 2 + 12 =
{ [ 35 ÷ 7 + 6 x 3 ] x 2 - 2 } x 2 + 12 =
{ [ 5 + 18 ] x 2 - 2 } x 2 + 12 =
{ 23 x 2 - 2 } x 2 + 12 =
{ 46 - 2 } x 2 + 12 =
44 x 2 + 12 =
88 + 12 = 100
