Today, I saw a lot of people donating money to people who didn't go to school on TV, remembering that there are about 65.438+0.3 billion people in China. If everyone saves 654.38+0 cents every day, then in this case, the national savings will be 6.5438+0.3 million yuan, and everyone will spend more than 6.5438+0.0 million yuan from primary school to university. According to this calculation, you can earn 654.38. If I had so much money, I would share it with the children!
It suddenly occurred to me that many hands make light work, but it also has disadvantages, right? Because if everyone wastes 65.438+0.3 billion more water every day, what a shame!
I did a small experiment: I dropped 1000 drops of water under the tap, weighing 200 grams, and I began to calculate:/kloc-0 130000000 divided by 1000 multiplied by 200 equals 26000000000 grams, and then 260000000 tons of water equals 260 years. I went to ask my parents, "1 ton of water can generate 100 kwh?" I thought about it and calculated that 260 tons of water can generate 26,000 kwh of electricity.
Whoa, whoa! I was shocked for five minutes. 260 tons of water can do so much! Therefore, from now on, all of us should save water and not waste a drop of water, and form a good habit of saving.
I believe that there is mathematics everywhere in life, and mathematics is used everywhere. As long as you are willing to learn mathematics, you can feel the happiness of mathematical thinking even in the game! ! !
