Step-by-step explanation:

(a) (-30)+10

= -20

(b) (-36) + (-9)

= -36-9

= -45

(c) 13 + [(-2) + 1]

13 + [-3]

= 13-3

= 10

(d) (-31) + [(-30)+(-1)]

= (-31) + (-31)

= -31-31

= -62

(e)[(-6 +5]+ (-2)+1

[-1] - 1

= -2

(f)50+(-5)

= 50-5

= 45

(g). (-49)+ 49

= 0

(h) [(-36)+12] + 3

= -24 + 3

= -21

Answer Step by step:

(a) (-30) + 10 = (-20)

(C) (-36)+(-9)  = (-45)

(C) 13+[(-2)+1]  = 13+(-1) = 12

(g) (-31) + [(-30)+(-1)]  = (-31)+(-31) = (-62)

(1) [(-6) +5]+[(-2)+1]  = (-1)+(-1) = (-2)

Chart

(b) 50+(-5)  = 45

(d) (-49) +49 = 0

(f) 0=(-12)

(h) [(-36) +12] +3 = (-24)+3 = (-21)

I HOPE THIS HELPS YOU OUT!!
