B. Menyelesaikan Perkalian dengan Cara Mendatar, Bersusun 0 0 0 0
Pendek, dan Bersusun Panjang.
Dalam menyelesaikan soal-soal perkalian dapat meng-
gunakan 3 cara, yaitu cara mendatar, tersusun panjang, dan
bersusun pendek. Perhatikan uraian berikut!
1) Cara Mendatar
Contoh: 6 x 35 = 6 x (30 + 5)
= (6 x 30) + (6 x 5)
= 180 + 30
= 210
Jadi, 6 x 35 = 210

Latihan 28

Kerjakanlah dengan cara mendatar!
1. 5 x 56= 5 x (... + 6)
= (5 x ...) + (5 x 6)
= ... + ...
= ...
2. 6 x 36 = ... x (30 + ...)
= (... x 30) + (... x ...)
= ... + ...
= ...
3. 7 x 28 = 7 x (... + 8)
= (7 x ...) + (7 x 8)
= ... + ...
= ...
4. 53 x 6 = (50 + 3) x 6
= (50 x ...) + (... x 6)
= ... + ...
= ...

5. 77 x 2 = (... + 7) x 2
= (... x 2) + (7 x 2)
= ... + ...
= ...
