数学日记大全 篇1

数学，像一个调皮的小精灵，我以前很讨厌数学，但当我认真学起的时候，还真挺有趣的。它不仅教会我知识，还带给了我 身活体健，也许你会说：”数学，怎么会2带给你身活体健呢？“那是因为，每次我一想到它，身体就非常有劲，所以才说是身活体健，嘻嘻，我是不是跑题了 ？

Mathematics, like a naughty elf, I hated mathematics before, but when I studied seriously, it was really interesting.It not only taught me knowledge, but also brought me to my life and health. May, So I said that I was living and healthy, hee hee, am I running a question?

学数学，让我们的大脑开发智力，同学们，你们喜欢数学吗？你懂数学吗？你明白质数与和数吗？如果你不明白的话，就让我给你讲讲吧！

Learn mathematics, let our brain develop intelligence, classmates, do you like mathematics?Do you understand mathematics?Do you understand the quality and the harmony?If you don't understand, let me tell you!

质数，就是 只有1和它本身两个因数的数，也叫素数，比如：2、3、5、7就是质数。

Quality numbers are the number of only 1 and itself, which are also called prime numbers, such as: 2, 3, 5, 7 are quality numbers.

合数，就是 除了1和它本身两个因数还一其它因数的数，比如：4、6、8、9、12、15、18就是合数。

The number of small numbers is the number of other factor except 1 and its own two factor, such as: 4, 6, 8, 9, 12, 15, and 18.

数学日记 篇2

看着橱窗里那个心仪已久的芭比公主，激动地心就要跳出了嗓子眼了，我使劲的的咬着嘴片，生怕一个不小心，狂喜的心从嘴里蹦出来。

Looking at the long -awaited Barbie princess in the window, I was excited to jump out of my throat. I bite my mouth hard, for fear of a accidental and ecstatic heart jumped out of my mouth.

那眼偷偷瞄向一旁的爸爸，只见老爸一手插在兜里，一手托着下巴，拇指来回的摸着，嘴角不经意间有丝诡异的笑。老爸这笑看着我心里直冷，难不成老爸又变卦了，上帝呀，神呀，如来佛祖，观世音菩萨呀，请您们一定要显灵帮助我这个人见人爱，花见花开，善良+乖巧的女孩吧！这可是我等了足足一年的生日礼物呀！

The dad was sneaking at the side, and I saw my dad inserted in his pocket with one hand, holding his chin with one hand, and touched the thumb back and forth. There was a strange smile on the corner of his mouth.Dad looked at me with a smile, and it was hard to become a dad to change the hexagram again.Kind+good girl!This is the birthday gift for a full year!

等不及神仙显灵，还是想靠自己吧，就拿我最擅长的“马屁功”来把我老爸拍晕吧！

If you ca n’t wait for the fairy, you still want to rely on yourself, take my dad to faint!

上前一步，一手挎住老爸的胳膊，用最最甜的声音说：老爸我知道你是这个世界上最亲我的人，比妈妈亲我一百倍，等我长大了，我会给爸爸挣很多很多的钱，买老爸最喜欢的东西。孝敬您！

Take a step forward, hold my dad's arm in one hand, and say the sweetest voice: Dad, I know you are the most close to me in the world, a hundred times more kissing me than my mother, waiting for me to grow up, I have grown up, meWill make a lot of money for dads and buy Dad's favorite things.Respect you!

还别说，这招还真管用，老爸先是眯着眼很受用的样子，然后又一脸的得意。

Not to mention that this trick is really in control. Dad first squints and looks very useful, and then proud.

真想要这个礼物？老爸终于发话，看起来有戏。

I really want this gift?Dad finally spoke and looked like a drama.

嗯嗯嗯，我的头点的跟小鸡啄米似的。

Hmm, my head is like a chick pecking rice.

想要可以。

Want.

谢谢老爸，就知道你是最亲我的。

Thank you Dad, you know you are the kiss of me.

不过……

but……

什么？什么？还有不过，不过什么？宝贝今天我没带钱；宝贝回头让你妈给你买；要不我们明年再买……一时间，N个不过就像雨后的竹笋以神九的速度从我的脑子里冒出来。

What?What?But, but what?Baby I didn't bring money today; the baby turned back to your mother to buy you; or we bought it next year ... For a while, n is just like the bamboo shoots after the rain come out of my mind at the speed of Shenjiu.

不过嘛，你的回答我一个问题？

But, your answer is a question?

我从神九中醒过来，结结巴巴的问:什么……什么……问题

I woke up from God's Jiuzhong and asked with a stutter: What ... what ... the question

今年你的生日是星期三，那30年后你的生日是星期几？

Your birthday this year is Wednesday. What day is your birthday after 30 years?

嘿嘿，老爸真狠，我暗想，不过想难到我，也不是那么容易的，为了我心爱的。礼物，我就是扳着指头算数也要数出来，何况我还有秘密招数，不过以防老爸耍赖，我还是要和老爸签订君子协议。

Hey, my dad is so ruthless, I thought, but I thought it was difficult, it was not so easy, for my beloved.Gifts, I just count the counting of my fingers. Besides, I still have secrets, but in order to prevent my dad from playing, I still have to sign a gentleman agreement with my dad.

老爸一听我要和他签订君子协议，脸上乐开了花，一口就答应了下来，我要是算出来就给我买，算不出来就不买，双方同意，协议即时生效。

As soon as my dad heard that I had to sign a gentleman agreement with him, I opened my face and agreed. If I calculated it, I would buy it for me.

呵呵呵，也太小看我了，没有金刚钻，我敢揽这瓷器活，老爸看我的。

Hehehe, too underestimated me, without diamond, I dare to take this porcelain work, my dad looks at me.

第一步骤我们先设定30年都是平年，每过一年，也就是52个星期加一天，30年也就是30天。

In the first step, we set up for 30 years in flat year, every year, that is, 52 weeks plus one day, 30 years is 30 days.

365/7=2…1

365/7 = 2 ... 1

第二步：计算出30年中有多少闰年，因为20xx——20xx年没有整百的年份，每四年一个闰年，一共有7闰年。

Step 2: Calculate how many leap years in 30 years, because there are no hundred years of 20xx to 20xx, a leap year every four years, a total of 7 leap years.

20xx年 20xx年 20xx年 20xx年 20xx年

20xx year 20xx 20xx year 20xx 20xx 20xx

20xx 年 20xx年

20xx year 20xx

也就是我的生日还要再加12天，结果就是：

That is, my birthday has to be added for another 12 days, and the result is:

30+7=37（天）

30+7 = 37 (day)

37/7=5…2

37/7 = 5 ... 2

我30年后的生日就是星期五。

My birthday after 30 years is Friday.

老爸看到我的结果是半信半疑，不过我们有“老师”求证，打开电脑上百度查询万年历呀。

The result of my dad was doubtful when I saw me, but we had a "teacher" to verify and turned on the computer to check the perpetual calendar.

呵呵呵，看着老爸的眼睛，我心里乐开了花，我最爱的芭比终于到手了。

Hehehe, looking at my dad's eyes, I was happy to bloom, and my favorite Barbie finally came.

亲爱的朋友，数学就像一个万花筒，它包罗万象，打开它就像走进一个多姿的世界，学好数学，真是其乐无穷，妙不可言呀！

Dear friend, mathematics is like a kaleidoscope. It is all -encompassing. Opening it is like walking into a versatile world. Learning mathematics is really endless and wonderful!

数学日记 篇3

8月1日，我和爸爸妈妈奶奶还有叔叔全家到蓬莱长岛去旅游。我们晚上9：00在新世纪坐车。第二天7：00到达长岛港。一共走了大约10个小时。

On August 1st, my parents and my grandma and my uncle had a family to travel to Penglai Long Island.We took a car in the New Century at 9:00 pm.Arrive at Long Island Port at 7:00 the next day.It took about 10 hours in total.

我们又乘船大约行驶了40分钟到达长岛。我们住在渔家小院，每一天吃海鲜，有贝壳肉，鱼肉馅饺子和炸黄花鱼。上午我们乘船出海打鱼，成人票每人40元，儿童票：身高超过1。4米是40元，没有超过是20元。

We took another 40 minutes to Long Island.We live in the small courtyard of the fishing house, eat seafood every day, have shell meat, fish stuffed dumplings and fried yellow flowers.In the morning, we went to the sea by boat. The adult ticket was 40 yuan per person.

我和哥哥得身高都没超过1。4米。这样我们全家三口正好是100元。我们一大家7口是240元。我望见渔民伯伯打上来一个海贝和一只海星。晚上我们逛海边夜市。妈妈给我买了一条玉石项链和用贝壳作的三只小狗。又给我的哥哥和妹妹买了三条玉石项链，一共花了50元钱。

My brother and I did not have more than 1.4 meters tall.In this way, the family of three of our family happened to be 100 yuan.A large family of 7 is 240 yuan.I saw the fisherman's uncle hit a sea shell and a starfish.At night we visit the sea night market.My mother bought me a jade necklace and three puppies made of shells.I bought three jade necklaces for my brother and sister, and spent a total of 50 yuan.

数学日记 篇4

春节已过去很久了，我和哥哥计划着想把我们多年积攒的钱（包括压岁钱）存入银行，使钱有更大的收益。因此，今天，我和哥哥先一起去了趟银行。

The Spring Festival has passed for a long time. My brother and I plan to deposit the money we have accumulated for many years (including the New Year's money) to the bank, so that the money has greater benefits.Therefore, today, my brother and I went to the bank first.

当我们一走进小区的工商银行，就看见电子大屏幕上的字，那上面便是币的存款利率情况，分为五种存法：整存整取定期存款、存本取息定期存款、零存整取定期存款、通知存款、活期存款。我们把利率情况一一抄到了小本子上。

As soon as we walked into the Industrial and Commercial Bank of the Community, we saw the words on the large electronic screen, which was the deposit interest rate of the currency.Zero deposit and complete deposit, notification deposit, current deposit.We copied the interest rates one by one.

回到家我们就迫不及待地和妈妈算了起来，我们的钱一共有3200元，一年期的利息是3200×4.14%=132.48元，扣除利息税132.48×0.05=6.62元，则利息净收入为132.48-6.62=125.86元；两年期的利息年收入是3200×4.68%=149.76元，扣除利息税149.76×0.05=7.49元，净利息为142.27元；三年的是3200×5.4%=172.8元，扣除利息税8.64元，净利息为164.16元；五年的是3200×5.85%=187.2元，扣除利息税9.36元，净利息为177.84元。从计算结果看起来是一年期的利息收入最少，五年的最多了。接着，我们又做起了一年和其他几年的比较，存两年的话，和一年会相差142.27-125.86=16.41元，存三年，相差164.16-125.86=38.3元，五年相差177.84-125.86=51.98元，如此看来，五年期的最合算。可是，转念一想，存的时间太长，假如碰到银行加息的话，我们又不能提前支取，因为提前支取只能算活期利率只有0.72%，那不是太亏了吗？如果存一年期的，感觉时间太短了一点，就在两年和三年期中选择吧，根据收入比较的结果，我们选择了三年期！

We can't wait to calculate with our mother when we get home. Our money has a total of 3200 yuan, the one -year interest is 3200 × 4.14%= 132.48 yuan, deducting the interest tax of 132.48 × 0.05 = 6.62 yuan, the net interest income is 132.48 -6.62 = 125.86 yuan; the annual income of the two -year interest is 3200 × 4.68%= 149.76 yuan, deducting the interest tax of 149.76 × 0.05 = 7.49 yuan, and the net interest is 142.27 yuan; The interest tax is 8.64 yuan, and the net interest is 164.16 yuan; the five years are 3200 × 5.85%= 187.2 yuan, the interest tax is 9.36 yuan, and the net interest is 177.84 yuan. From the results of calculation, it seems that the interest income of the year is the least, and the most five years. Then, we have made another comparison of one year and other years. If you save two years, the difference is 142.27-125.86 = 16.41 yuan in one year, three years, the difference is 164.16-125.86 = 38.3 yuan, and the difference between five years is 177.84- 125.86 = 51.98 yuan, so it seems that the five -year is the most cost -effective. However, when you think about it, the sale is too long. If we encounter a bank raising interest rates, we cannot withdraw in advance, because in advance, it can only be counted as 0.72%of the current interest rate. Isn't that too much loss? If you save one year, it feels too short. Choose it in two and three years. According to the results of income comparison, we have chosen the three -year period!

最后，我们将压岁钱存三年期的利息总收入再计算了一番，应该是164.16×3=492.48元。呵呵，我也从中学会了理财！

Finally, we calculated the total interest income of the three -year deposit of New Year's money, and it should be 164.16 × 3 = 492.48 yuan.Hehe, I also learned about financial management from middle school!

数学日记 篇7

昨天傍晚，我和姥姥去买西瓜，这次我的任务是自己跟瓜农讨价还价，买到好吃的西瓜。

Yesterday evening, I went to buy watermelon with me. This time my task was to bargain with melon farmers and buy delicious watermelon.

小区门口有一排卖瓜的摊子。我先来到第一家瓜摊前，因为这是我第一次独立买西瓜，我轻轻地问她：“西瓜多少钱？”“７毛。”我心想：西瓜怎么这么便宜呀？！我就说：“１元钱我买两个，行不行？”瓜农笑了：“一个都要五、六块钱呢，你一块钱就想买两个？７毛是一斤呐。”“哦。”我觉得特别不好意思。突然，我发现前面有一个瓜摊卖的是黄瓤西瓜，是我最喜欢吃的。“哈哈，这下帮我解围了！”我立刻拉着姥姥：“姥姥，我们去买黄西瓜吧。”然后，我飞快地跑过去。

There is a row of melon -selling stalls at the entrance of the community.I first came to the first melon stall, because this was the first time I bought watermelon independently, and I asked her gently: "How much is watermelon?" "7 hair." I thought: Why is watermelon so cheap?IntersectionI said, "I buy two for 1 yuan, can I do it?" Gua Nong laughed: "One requires five or six dollars, you want to buy two for one dollar? 7 hair is a pound." "Oh. "I feel particularly embarrassed.Suddenly, I found that there was a stall in front of the yellow watermelon, which was my favorite."Haha, this time I helped me solve it!" I immediately pulled my grandma: "姥, let's buy yellow watermelon." Then, I ran quickly.

这回，我有点经验了，我知道瓜农说的７毛钱是什么意思了！我立刻要去和他讨价还价。可姥姥说我不会，她就去买了两个西瓜，可也只便宜了５毛，也就是６毛５分一斤。

This time, I have a bit experienced, I know what the 7 cents that Gua Nong said is!I was going to bargain with him immediately.But I said that I wouldn't, she went to buy two watermelons, but it was only 5 cents cheaper, which was 6 cents and 5 cents a pound.

把西瓜送回家后，我还是不甘心，又自己去了另一个瓜摊。这次，我成功地谈好了价钱，我的成绩可比姥姥的好多了：原来也是７毛一斤，我砍到６毛５分一斤，挑了一个西瓜，一共是９斤，也就是９x0.65＝5.85（元），我又顺利地谈到5.5元，成交。

After sending the watermelon home, I was still unwilling and went to another melon stall myself.This time, I successfully talked about the price, and my grades were much better than 姥: it turned out to be 7 cents a pound. I cut it to 6 cents and 5 cents and pound..65 = 5.85 (dollars), I successfully talked about 5.5 yuan and the transaction.

这次买瓜收获可不小啊！

It ’s not small to get melon this time!

数学日记 篇8

今天我帮妈妈煎鸡蛋。我给你说说煎鸡蛋的时间，洗锅30秒，烧热油1分钟，拿鸡蛋要10秒，搅鸡蛋20秒煎鸡蛋5分钟，洗碟子30秒，把鸡蛋盛上30秒。我用了7分钟把鸡蛋煎好。

Today I help my mother fried eggs.Let me talk about the time of fried eggs, wash the pot for 30 seconds, heat the oil for 1 minute, take the egg for 10 seconds, stir the eggs for 20 seconds to fry the eggs for 5 minutes, wash the dish for 30 seconds, and put the eggs for 30 seconds.I used 7 minutes to fry the eggs.

然后，我跟妈妈说：“妈妈我把鸡蛋煎好了只用了7分钟。”妈妈说：“怎么那么快呀！”我回答：“我学了合理安排时间，它教了我，可以在同一时间内做许多样事情，数学真的很奇妙！

Then, I told my mother: "Mom, I fry the eggs for only 7 minutes." Mom said, "Why is it so fast!" I replied, "I learned a reasonable arrangement time.Doing a lot of things in the same time, mathematics is really amazing!

所以，我以后要学好数学。

Therefore, I have to learn math in the future.

数学日记200字 篇9

当黄老师教我们学了第三单元测量后，我心想：“我为什么不去测量一下其他东西的长度和重量呢？”于是，我开始测量了。

After Teacher Huang taught us to learn the third unit measurement, I thought, "Why don't I measure the length and weight of other things?" So I started to measure.

首先我发现成语词典的厚度有三厘米一毫米，《笑猫日记》这本书的长度有十八厘米六毫米，《淘气包马小跳》这本书厚六毫米等等……。这时，妈妈时进房间了，问道：“你在干什么？”“我在测量物体的长度。”“那我问你，你的滑板有多长？”“六十厘米。”“你的房间有多宽？有多长？”我用卷尺量了一下，说：“长三米九分米，宽三米五分米。”“你真棒，答对了。”妈妈说。最后我还说出了小货车的载重量是一吨等等。

First of all, I found that the thickness of the idiom dictionary is three centimeters and one millimeters. The length of the book "Smile Cat Diary" is eighteen centimeters and six mm, the book "Naughty Bao Ma Xiao Jump" is six mm thick and so on ...At this time, my mother entered the room and asked, "What are you doing?" "I'm measuring the length of the object."How long is the room? How long is it? "I measured it with a tape ruler and said," Three meters long nine meters, three meters and five -meter meters wide. "" You are awesome, answered right. "Mom said.In the end, I also said that the weight of the small truck was one ton and so on.

我做了这些测量后，发现我们身边处处有数学，只要仔细观察，就可以发现它的存在。

After I did these measurements, I found that there are mathematics around us. As long as you observe it carefully, you can find its existence.

数学日记 篇10

数学真是太神奇了，因为生活中它无处不在。

Mathematics is really amazing, because it is ubiquitous in life.

我坐在客厅环视四周，冰箱、电视机是长方形的，餐桌是正方形的，它们的每个角都是90度。我认真观察了一下，我那小方桌的角从侧面看是由两个等腰三角形组成的。墙上的挂钟是圆形的……，这些都与我刚学的'数学图案有关。

I was sitting around the living room. The refrigerators and televisions were rectangular, and the table was square. Each of them was 90 degrees.I observed it carefully. The corner of my small table is composed of two waist triangles from the side.The hanging clock on the wall is round ... These are all related to the 'mathematical pattern I just learned.

还有，生活中的人们经常要与数字打交道。例如：坐公交车要投币、去超市买东西要计算花费了多少钱，建筑师在建房子时，要用量角器、测绘仪等。

Also, people in life often deal with numbers.For example: how much money it costs to calculate by buses and buy things in the supermarket. When the architect under construction, the architect must use a quarrel, a surveying instrument, etc. when building a house.

生活离不开数学，数学来源于生活。我爱数学，我一定要把数学学好！

Life is inseparable from mathematics, and mathematics comes from life.I love mathematics, I must learn math well!
