The first answer: 1+ 1=2, the simplest answer, the classic answer of mathematics, and the conventional teaching answer.

The second answer: 1+ 1= 1, that is to say, 1 and 1 converge to get a larger capacity 1.

The third answer:1+1> 2, very cleverly avoided the classic answer, and did not create your own answer, which is a more pertinent answer mode.

The fourth answer: 1+ 1=0, the answer is unconstrained, and the specific answer reason can be understood by yourself.

The fifth answer: 1+ 1=3, which is similar to personification 1. Couples have one child and get three people.

Sixth answer: When someone asks how much 1+ 1 equals, ask a person, first tell me how much 2+2 equals, and if the answer is correct, I will tell you the answer of 1+ 1.

The seventh answer: You can take out a calculator and let the questioner do the math.
