Jawaban:
2. 20 - 12 × (-5) = 20 - (- 60)
= 20 + 60
= 80
3. "30 derajat Celcius dibawah nol" = -30°C
4. -27 + 204 : (-2) × (-3) = -27 + (- 102) × (-3)
= -27 + 306
= -279
5. -2 > -5
6. -10 < 10
7. -23 karena lawan positif = negatif
8. 15 × (-8) + 32 ÷ (-4) = -120 + 32 ÷ (-4)
= -120 + (-8)
= -120 - 8
= -128
9. -5, -4, -3, -2, -1, 0, 1, 2, 3
10. 210 - 34 +321 - (-341) + 32
= 210 - 34 + 321 + 341 + 32
= 176 + 321 + 341 + 32
= 497 + 341 + 32
= 838 + 32
= 870
