Today, I played darts with my sister. I found many math problems from this game!

A dart board has five circles, the innermost circle is a red heart, and shooting can get 10 points, the second circle 8 points, the third circle 5 points, the fourth circle 3 points, and the outermost circle 1 minute. My sister and I had a life-and-death contest.

Sister, she scored 3 points on the fourth lap for the first time. The second shot dropped, and she didn't score! Just as I was smiling from ear to ear, my sister suddenly made progress. Hit the key and get 10 points. I am not happy now. Sister, she got 13!

It's my turn I aimed for a long time. On the third lap for the first time, I scored 5 points. The second shot was not very good, only 3 points. If I want to surpass my sister, I have to shoot the innermost heart for the second or third time. As a result, I shot the second lap for the last time and won. I'm so happy!
