Mathematics in life


Today is a good day! My mother and I are going to go shopping at Jiasheng Plaza opposite the community.

When I came to the letter and supermarket in Jiasheng Square, my mother wanted to buy a bottle of detergent, so we went to the detergent area. At this time, my mother said to me: "I want to buy a bottle of citrus detergent now, there are different weights. Test you, the most affordable. I will buy the most affordable kind." I thought: This has What is difficult, I will know at a glance. I swept over and ruled out many bottles, leaving only two bottles.

I thought about it for a moment and looked at it carefully. I found that although the size of the two bottles of detergent was similar, the weight on the wrapping paper was different: one wrote 1.5 kilograms; the other wrote 1.3 kilograms. And their price is 12 yuan, of course, the 1.4 kilogram bottle is a little cheaper. I said to my mother, "This bottle is the cheapest. Just buy this bottle." At this time, my mother smiled and said to me with another bottle of detergent: "This bottle is 1.5 kilograms, 12.9 yuan, which is the cheapest." I took a closer look, it turned out to be super specials, oh! Miscalculated.

Everywhere in life, there is mathematics everywhere. If you are not careful, you will make mistakes. We must learn mathematics well.
