Perkalian Bilangan Bulat
PERKALIAN BILANGAN BULAT
Perkalian adalah penjumlahan yang berulang. contoh 15 + 15 + 15 + 15 = 4 x 15 = 60
rumus perkalian Bilangan Bulat:
+ x + = +
+ x - = -
- x + = -
- x - = +
contoh
1. 6 x 5 = 30
2. -3 x 2 = -6
3. 5 x (-7) = -35
4. -2 x (-3) = 6
4
Pembagian Bilangan Bulat
PEMBAGIAN BILANGAN BULAT
adalah kebalikan dari perkalian
rumus pembagian Bilangan Bulat:
+ : + = +
+ : - = -
- : + = -
- : - = +
contoh
1. 6 : 2 = 3
2. -12 x 4 = -3
3. 35 x (-7) = -5
4. -42 x (-3) = 14
