Jawab:

Soal 7

-15 + 24 – 9 x 12 – (-60)

= -15 + 24 – 108 + 60

= 9  - 108 + 60

= -99 + 60

= -39

Soal 8

-90 : 9 – (-45) : 5 x 15

= -10 – (-45) : 5 x 15

= -10 – (-9) x 15

= -10 – (-135)

= -10 + 135

= 125

Soal 9

15 + ((-15) x 5 – 75) : (-3)

= 15 + (-75 – 75) : (-3)

= 15 + (-150) : (-3)

= 15 + 50

= 65

Soal 10

24 + 48 : (-4) x 7 – (-40)

= 24 + (-12) x 7 – (-40)

= 24 + (-84) – (-40)

= 24 – 84 + 40

= -60 + 40

= -20
