Why 1 + 1 is equal 2? why it can't be 3?

So you said the formula getting the answer in 1+1=2 is A+B=C.. I dont think so. . Why i have 2 apples? why it can't be 3 apples or why it cant' be 4 or 5 and so on? Because that is the thing you already know when you grow up. And that is what you learned in your school.. And you never keep asking why? And you never ask your teacher why it is 2? why it cant be 3 or 4 or 5? I need the exact explanation and exact formula? Try to ask your teacher and try to get his/her opinion what would be the best formula in getting the answer in 1+1=2. I respect your explanation.. But it's not the best answer i looking for.

Apparently you did not read. If you have 1 dollar (A) and your friend has 1 dollar (B) then if you COUNT THEM it is 2 (C). You wanted a simple answer that is as simple as it gets. A+B=C No other way around it.

You are wrong. Don't assume anything about me. You think that is what I already knew or what I learned in school. Don't assume anything about me. How do you know that I went to school? You assumed. Why did I have to go to school? You need to provide an equation that PROVES that I went to school. I PROVED 1+1=2. You only assumed that I went to school without any equation. Maybe that is why you question a mathematical theory that proves A+B=C Provide me with the equation that proves the I have attended school.

What if i say i see 3 in my hand coz I assume 3 is 2 how can you explain that? Dont you think getting =2 to the question 1+1 is just part of our nature? As far as I know people dont have any exact explanation about getting the answer to this question.
