-124 x (500: 50)
= -124 x 10 = -124
4. 250 + (-8) x 25 = ....
Penyelesaian :
250 + (-8) x 25
= 250 + (-200)
= 250 - 200 = 50
5. -750 : 25 + (- 120) = ....
Penyelesaian :
-750 : 25 + (- 120)
= -30 + (-120)
= -30 - 120
= -150
6. 1750 - (-125) x (-8) = ....
Penyelesaian :
1750 - (-125) x (-8)
= 1750 + 125 x (-8)
= 1750 + (-1000)
= 1750 - 1000
= 750
7. -75 x 3 + (-5) x (-25) = ....
Penyelesaian :
-75 x 3 + (-5) x (-25)
= -225 + (-5) x (-25)
= -225 + 125
= -100
8. -150 + 250 : (-5) + 225 = ....
Penyelesaian :
-150 + 250 : (-5) + 225
= -150 + (-50) + 225
= -150 - 50 + 225
= -200 + 225
= 25
9. 750 - (-2) x (-250) + (-50) = ....
Penyelesaian :
750 - (-2) x (-250) + (-50)
= 750 + 2 x (-250) - 50
= 750 + (-500) - 50
= 750 - 500 - 50
= 250 - 50
= 200
10. 2 x (-75) + 250 - (300 : (-6)) = ....
Penyelesaian :
2 x (-75) + 250 - (300 : (-6))
= -150 + 250 - (-50)
= -150 + 250 + 50
= 100 + 50
= 150
11. -150 - 12 x 10 : 3 = ....
Penyelesaian :
-150 - 12 x 10 : 3

= -190
12. (21 x 13) - 170 + (- 102) = ....
Penyelesaian :
(21 x 13) - 170 + (- 102)
= 273 - 170 - 102
= 103 - 102
= 1
13. -20 x (75 + (- 50)) : (- 100) = ....
Penyelesaian :
-20 x (75 + (- 50)) : (- 100)
= -20 x ( 75 - 50 ) : ( - 100 )
= -20 x 25 : ( -100 )
= -500 : ( -100 )
= 5
14. (-115 + 45) x 27 : 30 = ....
Penyelesaian :
(-115 + 45) x 27 : 30
= -70 x 27 : 30
= -1890 : 30
= -63
15, 1.250 + 24 x 115 - 1.110 = ....
Penyelesaian :
1.250 + 24 x 115 - 1.110
= 1.250 + 2760 - 1.110
= 4.010 - 1.110
= 2.900
16. (20 - (- 30)) x (-5) = ....
Penyelesaian :
(20 - (- 30)) x (-5)
= (20 + 30) x (-5)
= 50 x (-5)
= -250
17. 175 - 15 x (-8) + (- 250) = ....
Penyelesaian :
175 - 15 x (-8) + (- 250)
= 175 - (-120) - 250
= 175 + 120 - 250
= 45
18. - 15 x (25 + (-23)) - (- 130) = ....
Penyelesaian :
- 15 x (25 + (-23)) - (- 130)
= -15 x ( 25 - 23 ) + 130
= -15 x 2 + 130
= -30 + 130
= 100
19. 54 : (21 - 3) + 60 : (-12) = ....
Penyelesaian :
54 : (21 - 3) + 60 : (-12)
= 54 : 18 + ( -5 )
