Xiaoming doesn't attend classes at school. The teacher asked him what one plus one equals. He didn't answer because he didn't understand. He went back to ask his mother, who was cooking. After listening, he looked at him and didn't expect the food to be burnt. Mother said, "The dish is burnt." Xiao Ming said, "It turns out that one plus one equals the dish is burnt." He went to ask grandpa again. Grandpa was watching TV. Grandpa is a little old and deaf. He didn't hear Xiaoming's voice. He was watching a football match. When he saw the goal scored by China, he said, "Oh, the ball is in the door!" Xiao Ming said, "It turns out that one plus one equals the goal. Why are their answers different? I'll ask my brother. " His brother was playing a game, and Xiao Ming asked him what one plus one was. His brother said, "You little fool, you don't even know one plus one." Xiao Ming said, "It turns out that one plus one equals you little fool who doesn't even understand one plus one." He went to ask grandma, who was reading the newspaper. Grandma said, "The newspaper is really nice," Xiao Ming said, "It turns out that one plus one equals the newspaper is really nice." The next day, he went to school and told his teacher, "Teacher, one plus one has several answers." The teacher asked him what one plus one was, and he said, "The dish is burnt." The teacher asked how to focus, and he said, "The ball is in the door." The teacher asked how to get the ball in, and he said, "You little fool, you don't know anything." He added, "This newspaper is really nice." The students all laughed at him.
