Math diary 150 is called something simple.
Today, my mother said that some guests might come to our house and we should prepare something to eat. Mom bought fruit, which is rich in dried fruit. Mom said that two guests were coming and asked me how to divide the apples. I thought about it. There are four people and two guests in my family, one is ***6 people. If you eat six apples, you may not finish them. In that case, it will be wasted. Why don't you cut the apple and eat half? I prepared three big apples, each of which was cut in half with a knife, and three became 1, haha, mom said I was right.

Chapter 2: Shopping in the supermarket

Today, my father and I went to the supermarket.

Dad took me to the street corner where vegetables were sold. We bought 2 Jin of cucumber, 1 Jin of tomato and 2 Jin of my favorite potato. On the way back, my father asked me, "There are just four cucumbers. There are three of us, but my mother went to Jinan. How many do we each eat? " Recalling the division I learned before, I said, "4 ÷ 2 = 2, everyone eats two." Dad asked again, "These four cucumbers cost 2 3 yuan cents each. How much is each cucumber? " I thought about it and said, "3 yuan's 2 angles are 32 angles, and 32 ÷ 4 = 8, each of which is 8 angles." Dad nodded, smiled and said, "You're right!" Today, I am so happy! I bought my favorite vegetables and learned math knowledge. It's killing two birds with one stone!

Article 3:

The Spring Festival is coming, and my mother takes me to the countryside to buy firecrackers. 7 yuan a set of firecrackers, Xiaohong said I bought 7, and my mother asked how much a * * *? Xiaohong wanted to mean to say 7×7=49 (yuan)

Mom says 50 yuan is enough? Xiaohong said that's enough. There is 1 yuan left.

Article 4: Buy chicken legs.

Today, I made an appointment with my classmates to have a picnic outside. I went to the supermarket and bought a bottle of 5 yuan. A loaf of bread 2 yuan, buy three; A pack of beef jerky 3 yuan 6 jiao; A hillbilly chicken leg, 2 yuan.

Aunt smiled and said to me, *** 15 yuan, I gave it to my aunt 15 yuan. When I walked out of the supermarket, I calculated: No, 5+2×3+3.6+2= 16.6 yuan, my aunt took 1.6 yuan, and I gave it back to her. Aunt said, "You are an honest boy"!

Mathematics can also make me understand the truth of being a man. I'm so happy.

Chapter 5: Fishing

Today, the weather is sunny, and my father took me fishing. Dad's fishing rod is 6 meters long, which is 600 centimeters. My fishing rod is relatively short, only 4 meters, which is 400 centimeters. Dad caught a lot of big fish, which was 35 cm long. And I only caught a few small fish about 10 cm. Although I am not as big as the fish my father caught, I am very happy today!

Article 6:

This morning, according to the "holiday plan" my father asked me to write, I started the "launching ceremony" of reviewing, practicing and strengthening mathematics! ?

I thought it was a little difficult at first, but it became easier and easier, and I thought math was so interesting! For example:?

There is a five-digit number, the lowest digit is 8, the highest digit is 3, one digit is twice the tenth digit, and the sum of the first three digits and the last three digits is 19. What is this five-digit number? ?

Answer:?

First calculate the highest and lowest digits of this five-digit number, then calculate the ten-digit number 8÷2=4, then calculate 8+4 =1219-12 = 7, and finally calculate 3+7 =1019. ?

I didn't like math before. It was boring. Now I think math is so simple and interesting! You will love math!
