Everyone has one’s favorite pet. As for me, I very love my dog named Pull. The dog is an Alaska dog with straight brown hair, blue eyes and big ear. He is said to be intelligent, loyal and obedient. Moreover, Pull is friendly and well-trained when I said “sit down” or “run around” he will do absolutely true. I remember the first day I have met Pull-my 12 birthday, he is a present given by my father. At that time, Pull was 2 years old, he was small and unfamiliar with my family’s members. Nowadays, he is an adult dog with good health and he seems to be one important member of my whole family. Pull and I usually have wonderful time together we eat, go shopping, walk in the sunrise and sunset, and play in a local park. As I’m the only child in my family, Pull is my best friend. Whenever I have trouble or whatever mistake I do, I always have him by my side. Although he is not able to talk, I feel the love and caring of him for me. Besides, Pull helps my mother much in household, he can hold a heavy bucket of water. Dog is not food; therefore I condemn the action of stealing dog by killing them with electricity in VN and selling it for some taverns. Dog is an animal for people to feed, love and care. Dog is not a product of any individual who wants to earn illegal money from it. Finally, it’s better for a house with a domes dog so that it brings happiness in addition to keeping your house save.

Số các số hạng của tổng trên là:                                    Ta thấy cứ sau 4 lượt nhân thì chữ số tận cùng lại trở về là 2 nên ta có:

    (2012-2):2+1=1006(số hạng)                                        1006:4=251(dư 2 lượt)      Vì 2.2.2=8 có chữ số tận cùng là 8 nên tích

                                                                                        có chữ số tận cùng là 8
