Question

{4×[(20-6) ×(85-16×5) - 4×(1+200:25)]}-5×(1+96:4)=​

Answer 1

{4 × [(20 - 6) × (85 - 16 × 5) - 4 × (1 + 200 : 25)]} -5 × (1 + 96 : 4) =​

= {4 × [14 × (85 - 80) - 4 × (1 + 8)]} - 5 × (1 + 24)

= ​[4 × (14 × 5 - 4 × 9)] - 5 × 25

= [4 × (70 - 36)] - 125

= 4 × 34 - 125

= 136 - 125

= 11

Answer 2

{ 4 × [ ( 20 - 6 ) × ( 85 - 16 × 5 ) - 4 × ( 1 + 200 : 25 ) ] } - 5 × ( 1 + 96 : 4 ) =

{ 4 × [ 14 × ( 85 - 80 ) - 4 × ( 1 + 8 ) ] } - 5 × ( 1 + 24 ) =

4 × ( 14 × 5 - 4 × 9 ) - 5 × 25 =

4 × ( 70 - 36 ) - 125 =

4 × 34 - 125 =

136 - 125 = 11
