1 = 2 - 1
1+1 = 2 - 1 +2 - 1
= 2 + 2 - 1 - 1
= 2 + 2 - 2
= 2 + 0
= 2
1 + 1 = 2 !!!

well you can say that 0 + 1 = 1
so the value of 1 is actually 1 since 0 is nothing and 1 unit plus 1 unit is 2.
but no you dont need to prove it

Why is it so hard to prove? Ok, if you but two things together you have 2. A woman and a man equals 2 people. I mean is this a joke.

What do you actually understand by 2, or how do you DEFINE 2?
