Calcula. (SOLUCIONES: a= +7 b= -2 c= +5 d= +8 )
a) (5 – 7) – [(–3) + (–6)] =
b) (–8) + [(+7) – (– 4) + (–5)] =
c) (+9) – [(+3) – (3 – 12) – (+8)] =
d) [(+6) – (–8)] – [(– 4) – (–10)] =
PD: hay que escribir el procedimiento

._. esto no párese de primaria xd
Explicación paso a paso:
a)(-2)-[(-9)]
(-2)+(+9)= +7
b)(-8)+[(+7)+(+4)+(-5)]=
(-8)+(+6)= -2
c)(+9)-[(+3)-(-9)-(+8)]
(+9)-[(+3)+(+9)+(-8)]
(+9)+(-4)=+5
D)[(+6)+(+8)]-[(-4)+(+10)]
[(14)] -(+6)
(14)+(-6)=+8
