Pembahasan =

(-50) – (-25) + 45 = (-50) + 25 + 45

(-50) – (-25) + 45 = (-25) +45

(-50) – (-25) + 45 = 20

5. 3 + (-7) – 4 = …

Jawaban = -8

Pembahasan =

(-14) – (-37) + (-25) = -14 + 37 + (-25)

(-14) – (-37) + (-25) = 23 + (-25)

(-14) – (-37) + (-25) = 23 – 25

(-14) – (-37) + (-25) = -2

7. Berapa hasil dari (255 : 5) + (-30) ?

Jawaban = 21

Pembahasan =

(255 : 5) + (-30) = 51 + (-30)

9. Berapa hasil dari (-10) – 5 x 15?

Jawaban = -85

Pembahasan =

(-10) – 5 x 15 = (-10) -75

(-10) – 5 x 15 = (-10) + (-75)
