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.
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.
107 in bold.
