MATERI BILANGAN BULAT
Operasi Hitung pada Bilangan Bulat
Penjumlahan:
Bilangan bulat positif + bilangan bulat positif = bilangan bulat positif
Bilangan bulat negatif + bilangan bulat negatif = bilangan bulat negatif
Bilangan bulat positif + bilangan bulat negatif = selisih kedua bilangan, tanda mengikuti bilangan yang nilainya lebih besar
2
.Pengurangan:
Mengurangi bilangan sama dengan menambahkan lawan bilangan tersebut. Contoh: 5 - (-3) = 5 + 3
Perkalian:
Bilangan positif × bilangan positif = bilangan positif
Bilangan negatif × bilangan negatif = bilangan positif
Bilangan positif × bilangan negatif = bilangan negatif
Pembagian:
Aturan tanda sama dengan perkalian

Sifat-sifat Bilangan Bulat
Komutatif:
Penjumlahan: a + b = b + a
Perkalian: a × b = b × a
Assosiatif:
Penjumlahan: (a + b) + c = a + (b + c)
Perkalian: (a × b) × c = a × (b × c)
Distributif:
a × (b + c) = (a × b) + (a × c)
