Answer 1

Explicação:

$-2+\{-5-[-2-(-2)^3-3-(3-2)^9]+5\}=\\ \\ -2+\{-5-[-2-(-8)-3-(1)^9]+5\}=\\ \\ -2+\{-5-[-2+8-3-1]+5\}=\\ \\ -2+\{-5-[+8-6]+5\}=\\ \\ -2+\{-5-2+5\}=\\ \\ -2+\{-7+5\}=\\ \\ -2+(-2)=\\ \\ -2-2=\fbox{ -4 }$

==================================

$[(7-2\times14):(-21)-(5-2)]:2=\\ \\ .[(7-28):(-21)-(3)]:2=\\ \\ .[(-21):(-21)-3]:2=\\ \\ .[+1-3]:2=\\ \\ (-2):2=\fbox{ -1 }$

=========================================

$100-\{[30-(5+1)^2]:6+9\}:8=\\ \\ 100-\{[30-(6)^2]:6+9\}:8=\\ \\ 100-\{[30-36]:6+9\}:8=\\ \\ 100-\{(-6):6+9\}:8=\\ \\ 100-\{-1+9\}:8=\\ \\ 100-\{+8\}:8=\\ \\ 100-1=\fbox{ 99 }$
