Calculation: 2005 * 2006-2006 * 200520052. What numbers should the seven Chinese characters "Happy New Year, Happy New Year" be changed into to make the following formula hold? Happy New Year's Day * OK = Happy New Year's Day 3. The seven-digit "2006" can be divisible by 4, 9 and 25 at the same time. What is this seven-digit number? 4. If the clock now shows 14 hour, then after the minute hand rotates 2006 times, the clock will be
On New Year's Day, Xiaoming played a game of "translating numbers into Chinese": he translated six Chinese characters "I like reading math books" in the following formula into mathematics, and the formula was established. Different Chinese characters represent different numbers. Can you translate them? I love reading * Math book = Math book * I love reading. Turn the six Chinese characters "I love reading math books" in the formula into math, and let the formula hold. Different Chinese characters represent different numbers. Can you translate them? I love reading * math book = math book * I love reading * 2. On New Year's Day, Xiao Liang played a game of "changing numbers": he wanted to change the word "Le" in the nine Chinese characters "Happy New Year to readers" in the following formula into the number "2", and the remaining eight Chinese characters into eight consecutive even numbers (unlimited digits), so that the formula was established. But he can't do that. Change it to eight even odd lines? This+publishing+desire+readers+Chinese New Year+fast+music =20 10.3. At the New Year's party, Kobayashi asked everyone to make a formula. She asked that the symbol "+"or ""be added before the continuous natural number 1, 2, 3, …, 20 10. Xiao Fang and Xiao Li play the game of number selection: the sum of natural numbers 1, 2, 3, …, 20 10 is odd. Now, any n of these 20 10 numbers (n
2. Ask for information about mathematics during the Spring Festival.
The words "Happy Spring Festival" stand for different numbers. Please replace these words with numbers to make the equation hold.
(Wish-Congratulations) * Spring * (Good Festival) =9
Zhu-(He Chun)-Anta = 1
Wish+Congratulations+Spring-(Festival+Beautiful) =9
Wish-Congratulations+Spring * (Good Festival) =7
Lights are on on New Year's Eve,
Colorful lights are bright and dazzling.
When the number is three or three, the integer is used up.
On the count of five, there is one left.
It is a coincidence that the number is seven seven.
There were still three missing when the number was eight or eight.
Please guess,
There are at least () kinds of lights.
Tongue twister:
There are hundreds of contestants, and Xiao Ming is the youngest.
To know how old he is, please look at the tongue twister:
"Age home age, age minus age.
Age multiplied by age, age divided by age;
All of them add up to exactly one hundred. "
Please calculate,
Xiaoming is () years old this year.
3. math diary Daquan has celebrated the Spring Festival.
The Chinese New Year is coming soon, and we have to make ends meet this year.
"Brother, settle the account", I don't care about anything else, just look at the red envelope I received. Find last year's ledger, match and calculate. This year, my uncle's family: Duck Egg, my aunt's family: 200 yuan, and then calculate the expenditure. Sister: 200 yuan, sister. Finally, make ends meet, and you will know how much you have made and how much you have lost this year. What's used in this? Math! For another example, during the Spring Festival, many relatives and friends will come to visit at home. At this time, we must prepare some new year's goods and firecrackers. Now, we have to turn to math for help. In this way, 5 yuan, a "flying monkey", a "five-colored tree" is 10 yuan, and "wonderful pen makes flowers" is 15.3 yuan. Coke 4 yuan, Milk 4.7 yuan and Juice 5 yuan.
However, if you use it wrongly, you will be in trouble: the Spring Festival is coming soon, and many people are willing to add joy to this festive occasion, buy land, build a house and move, but if the number is wrong, it will be miserable! For example, if you want to buy a 78-square-meter piece of land, but you accidentally miss the "7", your new home will become a "pigsty", and the area unit can't be wrong. If you add the word "Li" (square centimeter) after "square", there will be only "dogs" in your house. Although mathematics has made great contributions to us, it will still be a "dog" if we humans can't use it. Magical mathematics is actually around us. Let's start with every little thing around us, and you will find that this magical mathematics affects us all the time and helps us.
I love you-magic math! Second, the store Shen Every Spring Festival, I always receive many red envelopes. Of course, this year's Spring Festival is no exception.
I put all the lucky money I got and the pocket money I saved in peacetime into the bank. So far (once a year), I have saved several certificates of deposit.
I never asked about certificates of deposit before. Recently, I got a certificate of deposit with principal, tax and interest written on it, and I was stupid because I don't know anything about these terms! When I got home, I began to ponder.
But after thinking for a long time, I still have no clue, but I am full of doubts. I have no choice but to ask my grandmother and teacher shamelessly.
I asked doubtfully, "Grandma, what does the headmaster do?" "The principal is the original amount deposited in the bank, which is called the principal." Grandma said.
"Then why is the amount written on the certificate of deposit more than the actual principal after withdrawing money?" I asked again. "That's because the total amount on the deposit certificate after withdrawal is obtained by adding the original principal (interest minus 20% tax). You understand this time! " But I know a thing or two.
Grandma finally listed the formula and told me: for example, the annual interest of1000 yuan is X yuan, then the annual interest of 10000 yuan is1000 yuan. The tax is 100 x times 0.2.
100 x-( 100 x* 0.2) can get pure interest. The net interest plus the money actually saved is the total amount due (RMB).
I then asked, "Grandma, if I want to withdraw money in advance, how should I calculate the interest?" Grandma said: "In that case, the deposit interest will be calculated according to the current deposit interest, and it is best not to withdraw it in advance as a last resort." This time, I learned a lot about saving, broadened my horizons and increased my knowledge. But it makes me feel that mathematics is actually around us. We should learn math well, use math well, and use math to solve some problems that we often encounter in life.
Auntie, you have the wrong change! Today is February 6th, and Yuan Ruoda will celebrate the Spring Festival the day after tomorrow. In the evening, my parents and I went to Hualian Shopping Center to buy new year's goods.
Hualien is crowded with people. Of course, the goods in the supermarket are dazzling and dazzling! We selected the items as quickly as possible, including my favorite snacks, potato chips, Pepsi-Cola, nutritious breakfast cake, Jinri American ginseng and Great Wall dry red wine.
After paying the money and looking at the long receipt, I was dumbfounded. Mother asked me to compare the receipt with the goods to see if there were any mistakes.
I have a look, 4.5 * 2+35+17+100 * 2+6+15+25. These numbers seem to have life, and they dance around me, dazzling me.
After a long calculation, I finally got the result. A * * is 3 16 yuan 70 points. My mother paid 350 yuan, and she should get back 33 yuan's corner 3, but the clerk only found 32 yuan's corner 3.
Is this right or not? I recalculated, and the salesperson really missed 1 yuan. After I talked to my mother, she asked the clerk for 1 yuan.
I think: the clerk must have given me the wrong change because he is too busy and tired at work. Through this incident, I found that there are many interesting math problems in my life.
As long as you observe carefully, these math problems are around you. Fourth, the code table Liu Menglan After lunch today, Uncle Xiao Zhang asked me to help him remember the code table. In a word, I agree to do nothing.
20.2,21,20.7 Soon, the numbers ran all over the code table. I gave my own code table to Uncle Xiao Zhang, but he asked me to help him calculate it.
I thought to myself, forget it. So I said yes.
Each line of the code list has 1 1 spaces. Note every 1 1 spaces, and then add up each note. The first time I took notes, it was 224.2, but it became 244.9 when I checked it, so I changed 224.2 to 244.9.
But when I checked again, it became 204.4. Strange, 5 20.7, 1 20. 1, 1 2 1, 2 19.8, 1 20.2, 1 20, 20.7 *.
The result is 244.9-224.2=20.7, and I calculated 20.7 more. I see.
Just when I was happy, I found that a corner on the code table had been blurred by me. Mathematics in life is really not simple! 5. Amway Nutrilite's product Zhu Datian's mathematics is everywhere in life.
