Senior one math diary 50 words 1 20xx year x month x sunny.
I met many difficulties in the process of learning "Mathematics". Whenever I encounter difficulties, I want to give up, but I am curious about mathematics and always want to do the problem well. Difficulties came to me step by step, but I beat them again and again. It's really "where there is a will, there is a way".

I went to buy stickers for my brother last night and bought eight posters. I bought a puzzle of armored soldiers. Each poster is 1 yuan * * 8 yuan, and the puzzle 3 yuan is1* * 8+3 =1yuan. I got a price for the boss, which is cheaper 1 yuan. Here it is. My mother and I went home happily.
My mother bought school supplies for me 100 on Thursday. I happily took the money to the supermarket and bought an eraser 2 yuan, a schoolbag 32 yuan, a pencil box 5 yuan, a marker 12 yuan, and a bundle of pencils 10 yuan. The cashier asked me to calculate.
I remembered the calculation method of continuous subtraction in school mathematics class. The formula is: 100 yuan -2 yuan -32 yuan -5 yuan-12 yuan-10 yuan =6 1 yuan. The cashier praised me as a good boy who loves to study, and I smiled happily.
This morning, I came across a painting, which appeared in a book. I think this painting is very beautiful. When I enjoyed it, I found that there were many symmetrical pictures in it.
There are three landscape paintings, a four-legged table, a TV and three exercise books in this painting. I guess this must be the room of a child who loves to study.
As soon as I saw it, I knew: all three picture frames are symmetrical, so are the TV and exercise books!
I deeply realized that there is mathematics everywhere in life.

Today, I got to know the RMB, which is 100 yuan, 50 yuan, 20 yuan, 10 yuan, 5 yuan, 2 yuan, 1 yuan, 50 cents, 20 cents,/kloc-0 cents, 5 cents, 2 cents and/kloc-0 cents. There are five RMB 10 in 50 yuan, and five RMB 1 is 50, 1 = 10, 1 = 10. I also know that there are two kinds of RMB, one is paper money and the other is coins.
We should not scribble on the RMB, but cherish it. Save money from an early age, don't misuse it, and form good habits.
Today, we learned about RMB. 1 yuan has 10 1 angle, and 1 yuan has two 50 angles. 10 yuan contains 10 0 yuan, 10 yuan contains 2 5 yuan, 10 yuan contains 5 2 yuan, 100 yuan contains 2 50 yuan, 10 yuan contains 10.
Renminbi is divided into two denominations, paper money and coins. We should cherish RMB, don't scribble on it, scrimp and save at ordinary times, study hard and make progress every day.
On Saturday morning, some of my classmates came to my house to play. My mother suggested, "Do you want to have a skipping contest today?"
We are very happy. We agreed to mom's proposal and the game began. Xiaohong jumped 30 times, Xiao Fang jumped 25 times and I jumped 27 times. My mother asked us how many times we danced.
I remembered the continuous addition that the math teacher taught us to calculate. The same numbers should be aligned, starting with one digit. The column formula is 30+25+27=82 (pieces). My mother smiled happily at our answer.
Today, my mother gave me 50 yuan to buy fruits and vegetables. I bought a bag of apples, 6 yuan, a catty of cucumbers, 2 yuan, a catty of shrimps, 28 yuan and a sack of strawberries.

The salesman then asked, "How much do I give you?" I said I would get my 9 yuan money back. The salesman praised me as great, and I was very happy. When I got home, I gave the rest of the money to my mother, and her mother smiled with satisfaction.
