SIFIR 3
Hai, adik-adik semua...Hari ini kita akan meneruskan ke sifir 3. Sifir 3 mestilah dimulai dengan nombor 3 dan ia juga merupakan gandaan 3. Cuba adik-adik perhatikan bagaimana membentuk sifir 3 dan kemudian adik-adik cuba menjawab beberapa soalan di bawah:
1 x 3 = 3
2 x 3 = 3 + 3 = 6
3 x 3 = 3 + 3 + 3 = 9
4 x 3 = 3 + 3 + 3 + 3 = 12
5 x 3 = 3 + 3 + 3 + 3 + 3 = 15
Baiklah, berapakah jawapan 7 x 3? (A)19 (B) 21 (C) 23
Selamat mencuba....nanti kita bersambung di SIFIR 4
