Question

como se resuelve esto a) -8 +{-7 + [-2 + (-6 + 3) + 3]} b) -6 +{+4 -[+3 + (+5 - 6) - 4]} y c) 5 + {-3 + [+2 - (-6 + 8) + 5]} ayuda

Answer 1

-8 +{-7 + [-2 + (-6 + 3) + 3]} =
-8+(-7+(-2-6+3)+3)=
-8+(-7-2-6+3+3)=
-8-7-2-6+3+3=-17

-6 +{+4 -[+3 + (+5 - 6) - 4]}=
-6+(4-(3+5-6)-4)=
-6+4-3-5+6-4=-8

5 + {-3 + [+2 - (-6 + 8) + 5]}=
5+(-3+(2+6-8)+5)=
5+(-3+2+6-8+5)=
5-3+2+6-8+5=7
