In fact, all you have to do is quote a few numbers. The simplest thing is how much you spent on shopping.
I found it. If there are too many words or I'm not satisfied, I can write you another one.
Every time I walk into the campus, there will be a very eye-catching sign that says, "Learn mathematics in life and use mathematics in life." Yes, we can't do without math. If we don't study math, we will make a lot of jokes.
Take an incident that happened to me two years ago. That day, I got up early, and my mother asked me to help her go downstairs and buy some breakfast. Then I went downstairs with five dollars. I went downstairs, bought breakfast and paid for it. The boss said, "These will always be 2.5 yuan, and I will give you 2.5 yuan." Then he gave me the money. When I saw it, I quickly said, "No, no! If you give me less than one yuan, you should give me three yuan and fifty cents! " After hearing this, the boss was stupid, hesitated for a while, and said to me, "Little friend, you have miscalculated, which is the 2.50 yuan you are looking for!" " "As soon as I heard this, I was in a hurry to defend myself:" Uncle, you have miscalculated, obviously it is three yuan and fifty cents! "The proprietress on the side saw it and shouted at me in an angry dialect:" Look at this child, he is not young, how can he not even know the most basic arithmetic! " Everyone who ate there laughed "ha ha ha". I looked at it, ran home sadly and told my parents everything. My parents laughed their heads off. I said angrily, "Even you laugh at me!" Dad quickly explained, "It's not that we love to laugh at you, it's because you didn't understand and think about Jiao Yuanfen in mathematics. Then let me ask you what two pieces of 50 cents are equal to. "
"A dollar."
"How much are those two twenties?"
"Four dollars, of course."
Finally, I finally understood my carelessness in my father's explanation. Since then, I have never made the same mistake again.
Students, you must study math seriously. Mathematics is not that simple. After learning, you must remember: learn mathematics in your life and use it in your life.
