Why 1+1 equals 2.. . . Let’s talk boringly. . . .

Why 1+1 equals 2? This is the crystallization of the wisdom of our human ancestors. Because of the needs of life, our ancestors invented writing. With the needs of social development, we have the understanding of numbers. 1 is the initial number, and it goes up to 2, which means there are two 1s. The formula written is 1+1=2 . Conventions have become customs. People of all ages have believed this and educated their descendants in this way. It has been passed down to this day and teachers teach students in this way.
