It's New Year! Every household is round and prosperous, and the people of the whole country are immersed in the celebration of the New Year. People wear new clothes, eat New Year's Eve, set off fireworks and watch parties. What we children look forward to most is collecting lucky money! This year, there are "angry" and "rich" in my red envelope. How much money is there? I'm going to do the math.
On New Year's Eve, Yan Qiao's grandparents * * *, that is, my grandparents * * *, took out two red envelopes from the cupboard and handed them to me and my sister * * *, saying with a smile, "I wish you progress in your studies!" "Thank you grandparents!" We both said in unison. Then, Aunt took out two red envelopes from her uncle's pocket and stuffed them into ours. My mother also gave us a red envelope.
At night, I can't wait to open a bulging red envelope. Wow! I was pleasantly surprised to find that my grandfather gave me 1000 yuan, my uncle gave it to 600 yuan and my mother gave it to 1000 yuan! Haha, I'm rich! Calculate:1000+1000+600 = 2600, I have 2600 yuan!
On the third day of the lunar new year, we went to the pear garden to pay a New Year call to our grandparents. Grandma hugged me, then took out two red envelopes from her pocket and said, "Happy learning!" " "I opened it and found two 220 yuan ones." Hey? Why is there a change? ""Here's the change, and keep the rest for adults. " Grandma smiled and said, Oh, I see! "

On Sunday afternoon, I watched TV at home. My grandfather said, "I want to watch the weather forecast", so I switched the channel to the weather forecast. Reluctantly, I went to the kitchen and asked my grandmother to make an omelet. Grandma said today's meal is ready, don't bother me. I had to bow my head and play darts in my mother's room. As a result, darts flew into a box. I was dumbfounded at first sight. My grandmother saw it, and I beat some eggs. The topic is this: Grandma bought 35 eggs this morning, but you broke six. How many eggs are left? I did a mental calculation:10-6 = 4 * * *, 25+4 = 29 * * * *, and I got 29 quickly. You got it right. I won't hit you this time. Please don't damage anything next time, ok? I said remember, thank grandma for her tolerance.

Today, I was sick. I have a headache and a fever, and I can't even walk. After I told my father, my father took me to the village clinic to see a doctor. When I got there, an old doctor in his sixties took my temperature and said, "It's a good thing you came in time, otherwise the consequences would be unimaginable. Hang salt water! "
Dad asked the doctor, "How much is it?" "129 yuan." I saw that my father took out two pieces of money 100 and gave it to the doctor. The doctor gave my father a 50 yuan and two 10 yuan and 1 one-yuan coins. My father immediately put the change in his wallet. I sat on the sofa and saw that the doctor had not come to give me an injection, so I quietly helped my father calculate whether the money I got back was right. Dad paid 100+ 100=200*** yuan * * and should be able to get back 200-129 = 71* * yuan * * doctor's change: 50+10. Oh, yes, that's right On the way home, my father and I talked about it. My father said happily, "You ghost, don't forget to count money when you are sick!" " "

In the evening, I saw a problem in the Olympiad Book: the number of apple trees in the orchard is three times that of pear trees. Master Lao Wang fertilizes 50 apple trees and 20 pear trees every day. A few days later, all the pear trees were fertilized, but the remaining 80 apple trees were not fertilized. Excuse me: How many apple trees and pear trees are there in the orchard?
I am not intimidated by this question, but it can stimulate my interest. I think the apple tree is three times as big as the pear tree. If two kinds of trees are to be fertilized on the same day, Master Lao Wang will fertilize "20×3" apple trees and 20 pear trees every day. In fact, he only fertilizes 50 apple trees every day, which is 10, and the last 80 trees. Therefore, Master Lao Wang has been fertilizing for 8 days. 20 pear trees a day, 8 days is 160 pear trees. According to the first condition, there are 480 apple trees. This is to solve the problem with the idea of hypothesis, so I think the hypothesis method is really a good way to solve the problem.

Study fee: 430+200+81.3 = 711.3 * * *. Living expenses: I will drink about 5 cases of milk this semester, 5×30= 150*** yuan * * *. Every meal is about 2~3 yuan, and 2.5 yuan is 2.5× 3× 30× 5 =1125 * * *. "What else?" I bit my pencil and said to myself, "and your school supplies."
