2. Perkalian Bilangan (a) Perkalian Bilangan Oktal 6 7 7(8) x 7 6 7(8) = 6 6 7 1 1 1(8) Rincian :

6 5 1 6 0 7 6 6 7

6 7 0 7 1 1

7 7(8) 6 7(8) x 7 1 2 + 1 1(8)

Perkalian : 7 x 7 = 49 : 8 = 61 carry 6 7 x 7 + 6carry = 49 + 6 = 55 : 8 = 67 carry 6 7 x 6 + 6carry = 42 + 6 = 48 : 8 = 60 6 x 7 = 42 : 8 = 52 carry 5 6 x 7 + 5carry = 42 + 5 = 47 : 8 = 57 carry 5 6 x 6 + 5carry = 36 + 5 = 41 : 8 = 51 7 x 7 = 49 : 8 = 61 carry 6 7 x 7 + 6carry = 49 + 6 = 55 : 8 = 67 carry 6 7 x 6 + 6carry = 42 + 6 = 48 : 8 = 60

Penjumlahan : 1=1 7 + 2 = 9 – 8 = 1 carry1 0 + 7 + 1 = 8 + 1carry = 9 – 8 = 1 carry 1 6 + 1 + 7 = 14 + 1carry = 15 – 8 = 7 carry 1 5 + 0 = 5 + 1carry = 6 6=6

(b) Perkalian Bilangan Oktal 5 7 6(8) x 7 5 7(8) = 5 5 9 2 4 2 (8) Rincian :

5 3 5 5 1 6 5 5 9

5 7 1 6 2 2

7 6(8) 5 7(8) x 6 2 6 + 4 2(8)

Perkalian : 7 x 6 = 42 : 8 = 52 carry 5 7 x 7 + 5carry = 49 + 5 = 54 : 8 = 66 carry 6 7 x 5 + 6carry = 35 + 6 = 41 : 8 = 51 5 x 6 = 30 : 8 = 36 carry 3 5 x 7 + 3carry = 35 + 3 = 38 : 8 = 46 carry 4 5 x 5 + 4carry = 25 + 4 = 29 : 8 = 35 7 x 6 = 42 : 8 = 52 carry 5 7 x 7 + 5carry = 49 + 5 = 54 : 8 = 66 carry 6 7 x 5 + 6carry = 35 + 6 = 41 : 8 = 51

Penjumlahan : 2=2 6 + 6 = 12 – 8 = 4 carry1 1 + 6 + 2 = 9 + 1carry = 10 – 8 = 2 carry 1 5 + 5 + 6 = 16 + 1carry = 17 – 8 = 9 carry 1 3 + 1 = 4 + 1carry = 5 5=5
