On Saturday afternoon, when I finished my homework and had nothing to do, my mother gave me a question: Do you know the characteristics of multiples of 2? As soon as I heard it, I immediately replied: they are all even numbers. What are their characteristics? Mom asked again. Their units are all 0, 2, 4, 6 and 8. Mom said, you are really something. Do you know the multiple of 4? Do you know the characteristics? Now you have me stumped.

So, I found some multiples of 4 and found that their units are also 0, 2, 4, 6, 8, so I told my mother this rule. But my mother casually said a number, which overturned my discovery. Mom told me to keep watching, but I couldn't find it left or right. My mother reminded me: Look at the last two digits of these figures. I observed these figures according to the tips my mother gave me, and suddenly it dawned on me.

The original multiple of 4 is characterized by the fact that the last two digits of a number are multiples of 4, and this number is multiples of 4. Then, I tried several numbers, such as: 437,37 divided by 4=9, 1. According to the law, 437 is not a multiple of 4. Then I divide 437 by 4= 109 and 1, which is consistent with this feature.

The benefits of keeping a diary

First, practice good expression skills.

Keeping a diary every day is to express what you see and think in Chinese and put some scattered languages into written language, which not only exercises children's logical thinking ability, but also exercises their writing ability. You will find that children who are good at writing can also speak very well.

Second, cultivate observation ability.

The process of keeping a diary virtually exercises children's ability to observe life carefully and accumulate materials. He will use a pair of discerning eyes to discover the scenery in ordinary life. Over time, this observation will be forged into the ability to seize creative inspiration.

Third, improve the writing level.

Diary is free and unrestrained, but over time it will make a qualitative leap in children's writing ability. For beginners, trying to keep a diary is really a good way to improve their writing level.
