1. 11 + ( -8 ) x 9 = –61

2. ( -5 ) x 9 + 36 : ( -4)- ( -3) = –51

3. 20 : 5 x (-7) + ( -2) = –30

4. ( -11) x 9 – 81: 9 = –108

5. ( 17 + ( -2 ) ) x 4 – 28 : ( – 7 ) = 256

semoga membantu

Jawaban:

1. 11 + ( -8 ) x 9 = 11 + (-72)

= –83

2. ( -5 ) x 9 + 36 : ( -4) – ( -3) = -45 + -9 + 3

= -54 + 3

= –51

3. 20 : 5 x (-7) + ( -2) = 4 × (-7) + (-2)

= -28 + (-2)

= –30

4. ( -11) x 9 – 81: 9 = -99 – 9

= –108

5. ( 17 + ( -2 ) ) x 4 – 28 : ( – 7 ) = 15 × 4 – 28 : (-7)

= 60 – (-4)

= 60 + 4

= 64
