Hitunglah hasil operasi hitung campuran bilangan bulat berikut! a. 16-(-7)+9x (-4) b. 125 / (15 – (- 10)) + 25 c. 648: (-18)-(-11) x (-8) d. 34 × 8 + 420:7 – 156​

SOAL A.

16 – (-7) + 9 × (-4)

= 16 + 7 + (-36)

= 16 + 7 – 36 = 23 – 36 = (-13)

SOAL B.

125 ÷ (15 – (-10)) + 25

= 125 ÷ (15 + 10) + 25

= 125 ÷ 25 + 25 = 5 + 25 = 30

SOAL C.

648 ÷ (-18) – (-11) × (-8)

= (-36) – 88 = (-124)

SOAL D.

34 × 8 + 420 ÷ 7 – 156

= 272 + 60 – 156 = 332 – 156 = 176
