b) -5 + ( -6) – (- 5) + (- 9) - (+7) + ( -10) + 7 – 12 =
c) [ -6 + (4 + 2) – ( -9)] – [ (-4) – (+7-5) + (-12)] +7 -15 =

Answer 1

Respuesta:

a) =14

b)=-37

Explicación paso a paso:

a=15+ {- 11 + [ - 7 + (- 4 + 8) + 3 + 6] + 4}

a=15+{-11+[-7+4+3+6]+4}

a=15+{-11+6+4}

a=15+ (-1) = 14

b=-5-6-(-5)+(-9)+(-10)-12

b=-5-6+5-9+(-10)-12

b=-5-6+5-9-10-12

b=-6-9-10-12=-37
