Answer 1

Respuesta:

a. + 5 + 6 + 8 + 7 + 9=

5 + 6 + 8 + 7 + 9=

11+15+9=

26+9= 35

b. – 6 – 8 – 7 – 3 – 4 – 2=

-14-10-6=

-24-6= -30

c. (– 5) + (– 7) + (– 6) + (– 4)=

-12 + -10= -22

d. (+4) + (+9) + (+3) + (+10)=

4+9+3+10=

13+13= 26

e. (–6) – (–5) – (–7) – (– 12)=

-6+5+7+12=

-6+12+12=

-6+24= 18

f. (+6) – (+15) – (+11) – (+31) – (+15)=

6-15-11-31-15=

6-26-46=

6-72= -66

g. (– 15) + (+12) – (–18) – (+25) + (–19)=

-15+12+18-25+-19=

-15+30-44=

-59+30= -29
