Whoever gives me the best explanation as to why 1+1=2 will win brainliest

Because someone said so
Also because 2-1=1

Well it is because of counting. think of an empty jar, and you place a button or something in there how many do you have? you have one but lets say you added another thing how many does that give you then? it gives you two, so that is why 1+1 equals 2.
