Color of mathematics

In the morning, the bright red sun reveals half a smiling face, and the harmonious sunshine spreads all over the world. I'm in a really good mood. Suddenly I got a call from my grandfather and asked me to calculate 9.5 plus 99.5 skillfully. I told him at once: nine plus 99, plus one, isn't it 109? Grandpa said my algorithm was not clever, and it would be much easier to calculate if I rounded up and reduced the score. I immediately interrupted grandpa and told him:10+100-1=109 (yuan). At this time, my grandfather praised me and said that I was still smart. This is the math problem in the morning. I marked the math in red.

In the morning, my father came back from the bank to pay the electricity bill and asked me to calculate the electricity bill. Electricity consumption ranges from 1079- 1279 (kwh), and the unit price per kwh is 0.38 yuan. I calculated the 200 kWh carefully, and I changed the unit price to a score of 38/ 100. The formula is 200×(38/ 100), which is probably the first. Dad said yes, just like a computer. I was so proud that it was nearly noon at this time, and I decided that math was yellow.

In the afternoon, my sister and I cut watermelons at home, and then cut half a watermelon evenly into two knives, and the two knives are 2/3. I asked my sister how many parts are these two watermelons? My sister is only in the first grade, of course not. I told her that the whole watermelon is 1, the first score is 1/2, and its score is 2/3. The result of multiplication is that these two copies are 2/6 of the whole watermelon, and after the score is reduced, it is 1/3. At this time, I remembered that my grandfather once said that the seven colors of sunlight are all white, so this math is white.

In the evening, under the blue starry sky, I watch TV with my mother. I never understood how archaeologists calculated the height of the big Al dinosaur from the fossil leg bones. Mom said that this kind of blue math will be natural when you grow up.

There is too much math in life. It's really colorful, and it appears at your side at any time. I like math. I want to learn math well.
