Operasi Bentuk Aljabar
By Yoventa Nahak
22
Sifat-sifat Operasi Hitung Aljabar
1. Sifat Komutatif
a + b = b + a
a x b = b x a
2. Sifat Asosiatif
a + (b + c) = (a + b) + c
a x (b x c) = (a x b) x c
3. Sifat Distributif (perkalian terhadap penjumlahan)
a x (b + c) = a x b + a x c
atau
a(b + c) = ab + ac
