Answer 1

Respuesta:

a)16 b)25 c)-23 d)0 e)-30 f)0

Explicación paso a paso:

a) (-3)+(+10)-(-5)+(+4)

(-3)+10-(-5)+4

-3+10+5+4

16

b) (+15)-(-7)+(-10)+(+13)

15-(-7) +(-10) +13

15+7+(-10) +13

15+7-10+13

25

c) (+10)+(-16)-(-3)-(+20)

10+(-16) -(-3)-20

10-16-(-3)-20

10-16+3-20

-23

d) (-3)+(-2)+(+18)-(13)

(-3) +(-2) +18-13

-3+(-2) +18-13

-3-2+18-13

0

e) (-5)-(+12)+(-3)+(-10)

(-5) -12+(-3)+(-10)

-5-12+(-3) +-10)

-5-12-3+(-10)

-5-12-3-10

-30

f) (+7)-(-18)-(+10)+(-15)

7-(-18)-10+(-15)

7+18-10+(-15)

7+18-10-15
