Answer 1

$60\div \{\sqrt{4}\times [-7+18\div (-\sqrt{9}+12)]\}-[7\times (-3)-18\div (-2)+\sqrt{1}] =$

$60\div \{2\times [-7+18\div (-3+12)]\}-[7\times (-3)-18\div (-2)+1] =$

$60\div \{2\times [-7+18\div 9]\}-[7\times (-3)-18\div (-2)+1] =$

$60\div \{2\times [-7+2]\}-[7\times (-3)+9+1] =$

$60\div \{2\times [-5]\}-[-21+9+1] =$

$60\div \{-10\}-[-21+9+1] =$

$-6-[-21+9+1] =$

$-6-[-11]=$

$-6+11=$

$5$
