Answer 1

We must simplify the next

`14+\mleft\lbrace-2+3\lbrack1+3(-6-2\mright)\rbrack\rbrace`
`\begin{gathered} 14+\lbrace-2+3\lbrack1+3(-6-2)\rbrack\rbrace \\ =14+\lbrace-2+3\lbrack1+3(-8)\rbrack\rbrace \\ =14+\lbrace-2+3\lbrack1-24\rbrack\rbrace \end{gathered}`
`\begin{gathered} =14+\lbrace-2+3\lbrack-23\rbrack\rbrace \\ =14+\lbrace-2-69\rbrace \end{gathered}`
`\begin{gathered} =14+\lbrace-2-69\rbrace \\ =14-71 \\ =-57 \end{gathered}`
