## Why Every Proof that 0.999… = 1 is Wrong

The proof made me look at the ceiling (lol). It sounded very convincing for a few seconds. Watch and watch closely til the end.

You have probably seen, or even been challenged to explain the proof of **1 = 2** shown in the table below. If you have no idea why the proof seems valid, it is now your opportunity to look at it and probe about it. Try to see if you can identify what is wrong with it before proceeding.

We have discussed the division by **0 **is undefined, and this operation is not permitted.

In step number 5, we divided *(a + b)(a-b) = b(a-b)** *by ** a – b**. Now from step 1,
