For example, mom goes to buy fruits and vegetables, goes to the publishing house to reply to the manuscript ... and so on, all of which need math. There are many interesting mathematics in life, waiting for us to discover and explore.
During the summer vacation, my parents and I went to my cousin's house to play. I was thirsty on the road, so my father had to buy mineral water from the nearby grocery store. There is a rule in the grocery store: if you buy three bottles of mineral water, you can get a bottle of mineral water, and the price of a bottle of mineral water is 1 yuan. When my father saw it, he took out 10 yuan and gave it to the grocery store owner, saying, "The boss bought 10 bottle of water." When I got the water, I drank it hungrily, and soon I drank two bottles. Before I came to my senses, there were several empty bottles. Dad asked me, "Lingling,1how many bottles of mineral water can 0 yuan exchange?" I think: I drank 10 bottle of water, 9 empty bottles were replaced with 3 bottles of mineral water, 3 empty bottles were replaced with 1 bottle of mineral water ... and there were two empty bottles left. I happily said to my father, "Dad, I have worked it out. Yes 14 bottle of mineral water, and there are 2 empty bottles left. " Dad smiled and said, "Think again!" I said thoughtfully, "We can borrow an empty bottle from the grocery store owner and return it to the boss after drinking it. Oh! We can drink 15 bottles of mineral water. " Dad nodded in praise.
Mathematics is to use it flexibly and integrate theory with practice. Only by mastering the knowledge of mathematics can mathematics serve us better. So we should learn mathematics well and make mathematics a good helper in our study and life.
