PENGURANGAN BILANGAN BULAT "AYO BERLATIH" MTK 4/2
AYO BERLATIHPENGURANGAN BILANGAN BULAT
INGAT !!!
Contoh:
Tentukan hasil pengurangan bilangan bulat berikut:
a. (–45) – (–5) = . . . .
b. 99 – (–11) = . . . .
c. 125 – 25 = . . . .
d. (–150) – 50 = . . . .
Jawab:
a. (–45) – (–5) = (–45) + 5 = –40
b. 99 – (–11) = 99 + 11 = 110
c. 125 – 25 = 100
d. (–150) – 50 = (–150) + (–50) = –200
A. Mari mengurangkan bilangan bulat berikut dengan
garis bilangan.
1. 5 – (–8)
Jadi, 5 – (–8) = . . . .
2. (–4) – 7
Jadi, (–4) – 7 = . . . .
3. (–6) – (–3)
Jadi, (–6) – (–3) = . . . .
4. 10 – 9
Jadi, 10 + (–9) = . . . .
5. (–4) – 4
Jadi, (–4) – 4 = . . . .
B. Mari menghitung pengurangan bilangan bulat
berikut ini. (TANPA GARIS BILANGAN)
1. 20 – 15 = ......
2. (–25) – 12 = ......
3. 36 – (–13) = ......
4. (–60) – 32 = ......
5. (–66) – (–33) = .......
6. (–75) – 75 = ......
7. 142 – 241 = ......
8. (–670) – (–170) = ......
9. (–1.444) – 556 = ......
10. 2.536 – (–1.336) = .......
