Aturan operasi bilangan bulat
1. Ubah - (- menjadi +
2. Ubah + (- menjadi -
3. Jika Jenisnya S A M A, maka bilangan dijumlah
4. Jika Jenisnya B E D A, maka bilangan dikurang (besar-kecil)
5. Jenis hasil = jenis angka terbesar

Contoh aturan 3
Jika Jenisnya S A M A, maka bilangan dijumlah
32
Multiple Select
Tandai setiap operasi yang bilangan-bilangannya berjenis sama
7 + 9
-7 + 9
-7 - 9
7 -9
33
7 + 9 --> keduanya berjenis positif
-7 + 9 --> 7 berjenis negatif sedangkan 9 berjenis positif
-7 - 9 --> keduanya berjenis negatif
7 - 9 --> 7 berjenis positif sedangkan 9 berjenis negatif
34
Contoh aturan 4
Jika Jenisnya B E D A, maka bilangan dikurang (besar kurangi kecil)
35
Multiple Select
Tandai setiap operasi yang bilangan-bilangannya berjenis berbeda
7 + 9
-7 + 9
-7 - 9
7 -9
36
7 + 9 --> keduanya berjenis positif
-7 + 9 --> 7 berjenis negatif sedangkan 9 berjenis positif
-7 - 9 --> keduanya berjenis negatif
7 - 9 --> 7 berjenis positif sedangkan 9 berjenis negatif
37
Contoh aturan 5
Jenis hasil = jenis angka terbesar
38
Multiple Select
Tandai setiap operasi yang mengasilkan bilangan positif
7 + 9
-7 + 9
-7 - 9
7 - 9
39
7 + 9 --> angka terbesar adalah 9 maka hasilnya positif
-7 + 9 --> angka terbesar adalah 9 maka hasilnya positif
-7 - 9 --> angka terbesar adalah -9 maka hasilnya negatif
7 - 9 --> angka terbesar adalah -9 maka hasilnya negatif
40
Multiple Select
