What is 1 1?

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. He listened and looked at him, but he didn't expect the dishes to be burnt. Mother said, "The food is burnt." Xiao Ming said, "It turns out that one plus one equals the food paste." He went to ask grandpa again. Grandpa is watching TV. Grandpa is a little old and deaf. He didn't hear Xiaoming's voice. He is watching a football match. When he saw China's goal, he said, "Oh, it's a goal!" 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 is playing a game, and Xiao Ming asks him how much one plus one is. 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, a little fool who doesn't even know one plus one." He went to ask his grandmother who was reading the newspaper. Grandma said, "The newspaper is really nice," Xiaoming said. "It turns out that one plus one equals the newspaper is really nice." The next day, he went to school and said to the teacher, "Teacher, one plus one has several answers." The teacher asked him what one plus one was, and he said, "The food 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 good." The students laughed at him.
