Doesnt it go back to euclidian rules of geometry, ie a thing of length one unit + a thing of length one unit = a thing of length 2 units, am i right???

I did this in yr 10
let a = b
a² = ab Multiply both sides by a
a² + a² - 2ab = ab + a² - 2ab Add (a² - 2ab) to both sides
2(a² - ab) = a² - ab Factor the left, and collect like terms on the right
2 = 1 Divide both sides by (a² - ab)
let a = b
a² = ab Multiply both sides by a
a² + a² - 2ab = ab + a² - 2ab Add (a² - 2ab) to both sides
2(a² - ab) = a² - ab Factor the left, and collect like terms on the right
2 = 1 Divide both sides by (a² - ab)

i know the proof is quite complex but I saw the newton proof for this but didnt understand it so i thought someone may know a method which i could understand

therefore, divide the whole lot by 2
1 + 1 = 2

I don't think you need to prove it, it's just definition.

who asked u to prove 2 = 1?

2 + 2 = 4 we know this to be true
therefore, divide the whole lot by 2
1 + 1 = 2

That wasn't the proof he wanted. He wanted 1 + 1 = 2, not 1 = 2.

Proof does exist... and there are many versions of it
