D) (-2)-(-4)-(+7)-(-2)+(-12)
Me ajudem por favor

Answer 1

A)(+2)+(-6)-(-5)+(+2)

2−6−(−5)+2

= −4−(−5)+2

= 1 + 2

= 3

B)(+3-(+5)-(-10)

= −2 −(−10)

= 8

C)(-5-(-8)+(-7)-(-9)+(-3)

= 3−7−(−9)−3

= −4−(−9)−3

= 5 − 3

= 2

D)(-2)-(-4)-(+7)-(-2)+(-12)

−2−(−4)−7−(−2)−12

= 2−7−(−2)−12

= −5−(−2)−12

= −3−12

= −15
