1+ 1 equals three or four jokes.

One day, Xiao Ming's teacher asked Xiao Ming how much 1+ 1 equals. Xiao Ming said I don't know. The teacher said to go back to your parents to teach you. When Xiao Ming comes home, he asks his mother what 1+ 1 is. At that time, her mother was playing mahjong and said two cakes. Xiao Ming went to ask her father for a drink and said it was cool. Xiao Ming then went to ask her sister that she was eating cookies and said they were delicious. Xiao Ming went on to ask her sister, who finished her homework, and Xiao Ming went on to ask her brother. At that time, I called downstairs and waited for you. The next day, the teacher asked Xiao Ming, 1+ 1 equals several cakes, and the teacher then slapped him twice. Xiao Ming said it was cool, and the teacher got angry and took Xiao Ming outside to ask him how delicious 1+ 1 was.
