Let's solve it by applying BODMAS Rule.
B = Bracket
O = Of
D = Division
M = Multiplication
A = Addition
S = Subtraction
First solve the brackets, then do division, multiplication, addiction and in last subtraction.
=> 21/7 - [6/5 + {21/10 × (57/10)}]
=> 21/7 - [6/5 + (21/10 × 57/10)]
=> 21/7 - [6/5 + (1197/100)]
=> 21/7 - (6/5 + 1197/100)
=> 21/7 - (1.2 + 11.97)
=> 21/7 - (13.17)
=> 3 - 13.17
=> - 10.17
