Jawaban:

1.

a. 12 -((15-(-16)) = 12 - (15 +16)= 12 - 31

12 - 31 = - 19

b. 11 -(-22)+(-10) = 11 + 22 -10 = 33 -10

33 - 10 = 23

c. -34 - ((45-(-28)) = -34 - ( 45 + 28)

-34 - 73 = -34 + -73 = - 107

d. -12 + 18 -(-15) = -12 + 18 + 15

6 + 15 = 21

e. -15 - 8 + (-7) = -15 + -8 + -7

-23 + -7 = -30

2.

a. 9 x -6 = - 54

b. -9 x 11 = -99

c. -13 x -17 = 221

d. -24 :(4:(-2) = -24 : -2 = 12

e. (-64 : (- 8)) : -4 = 8 : -4 = -2
