**Introduction**

Since it’s Christmas let us break a leg for a while from learning and thinking about serious mathematical proofs. In this post, I am going to prove something *fun* — something that is counterintuitive. If you love challenge, think about the proof and justify why it is right or wrong.

In this post, I will prove that two equals one.

**Theorem: **2 = 1

**Proof**

Let .

Multiply both sides by :

Add to both sides:

Subtract from both sides: .

Factor out :

Divide both sides by : .

I see the mistake 🙂
