Segunda expressao 41+{25-[14+(-17+28)]-10}=

Answer 1

1) -14+{-[-4+(-2)+(-50+39)]}=
=-14+{-[-4-2-11]}=
=-14+17=
=+3

2) 41+{25-[14+(-17+28)]-10}=
=41+{25-[14+11]-10}=
=41+{25-25-10}=
=41-10=
=31

Answer 2

-14+{-[-4+(-2)+(-50+39)]}=
 -14+{-[-4-2)+(-11)]}=
  -14+{-[-6-11)]}
   -14+ 17)]}
    -14 +17=
        +3

 41+{25-[14+(-17+28)]-10}=
  41+{25-[14+(+11)]-10}=
 41 +{25-[25]-10}=
 41 +{25-25]-10}=
41 + 0-10=
  41-10=
    31
