11.

• = -150 - 12 × 10 : 3
• = (-150) - 12 × 10 : 3
• = (-150) - 120 : 3
• = (-150) - 40
• = -( 150 + 40 )
• = -190

12.

• = ( 21 × 13 ) - 170 + (-102)
• = ( 273 ) - 170 + (-102)
• = 273 - 170 + (-102)
• = 103 + (-102)
• = ( 103 - 102 )
• = 1

13.

• = -20 × ( 75 + (-150) ) : (-100)
• = (-20) × ( 75 + (-150) ) : (-100)
• = (-20) × ( -75 ) : (-100)
• = ( 20 × 75 ) : (-100)
• = 1.500 : (-100)
• = -( 1.500 : 100 )
• = -15

14.

• = (-115 + 45 ) × 27 : 30
• = -( 115 - 45 ) × 27 : 30
• = (-70) × 27 : 30
• = -( 70 × 27 ) : 30
• = (-1.890) : 30
• = -( 1.890 : 30 )
• = -63

15.

• = 1.250 + 24 × 115 - 1.110
• = 1.250 + 2.760 - 1.110
• = 4.010 - 1.110
• = 2.900

Answer 2

Jawaban:

11. -150 - 12 × 10 ÷ 3

= -150 - ( 12 × 10 ) ÷ 3

= -150 ( 120 ÷ 3 )

= -150 - 14

= -190

12. ( 21 × 13 ) - 170 + ( -102 )

= 273 - 170 + ( -102 )

= 103 + ( -102 )

= 1

13. -20 × ( 75 + ( -50 ) ÷ ( -100 )

= -20 × ( 25 ÷ ( -100 )

= -30 × -0.25

= 7.5

14. ( -115 + 45 ) × 27 ÷ 30

= -70 × 27 ÷ 30

= -70 × 0,9

= - 63

15. 1.250 + 24 × 115 - 1.110

= 1.250 + ( 24 × 115 ) - 1.110

= ( 1.250 + 2760 ) - 1.110

= 4.010 - 1.110

= 2900
