Math composition in life (1) There is a lot of math in life, but I also found one. The winter vacation is coming, and winter vacation homework takes turns to distribute it. How much did I rewrite in a day? I want to write two pages a day and four pages in English, because the number of pages in a day is 37, so 37/2= 18.5 (day) is about 19 days, while English is 6 1 614 =15. After a few days, I learned well. My father took me to Dicos. We wanted crispy fried chicken and we got a 20% discount card.
There are countless mathematics in life, waiting for you and me to discover!
One day, I was doing my homework quietly at home. After a while, I finished my homework. I went to watch TV. I saw those colorful bubbles on TV. They are beautiful. I turned off the TV and went to find four friends. We made bubble water with our own soapy water. We blow big and beautiful bubbles together. I said, "Let's count how many we played together!" " Divide the bubble we blow together by 5 and see what it is.
The next day I blew 1 1, Xiaohong blew 10, Xiaoming blew 15 and Xiaojun blew 14. We will use it; 11+10+15+14 = 50. In use; 50 divided by 5= 10 (pieces). Let's talk at the same time; Ha ha! Equal to 10. ; Looking at these beautiful big bubbles, we are all deeply attracted by them. It seems that we all forgot to go home.
Today, my mother took me to the supermarket to buy food. When I arrived at the supermarket, my mother asked me to choose my favorite dishes.

A corn 3 yuan, two 6 yuan, eggplant 2 yuan 3 jiao, three tomatoes 2 yuan 7 jiao, two cucumbers 1 yuan 9 jiao. Mom said, "Baby, let's figure out how much it costs first. Is 15 yuan enough?" I did a quick calculation in my mind: "(2×3)+(2.3+2.7)+ 1. 9 "should be 12 yuan 90 points. I quickly reported the results to my mother. 15 yuan is enough. Is there 1 cent left for 2 yuan?
My mother looked at me and smiled and said to me, "It's really important to learn math well in life!" " "
